Hmm - we are still in fight w.r.t. upstreaming gcc fully (ARCv2 gcc support)
although ARCompact has been there for some time. binutils upstream should work -
I'll check why the buildall stuff fails.

We currently have our tools on github but presume that won't work for you due to
non canonical location / version !

Currently HD-audio (both ASoC and legacy ones) are the only drivers
providing the link timestamp.  In the recent code, it's PCM
get_time_info ops, so you can easily grep it.

Description: Binary data

[PATCH 3/6] kexec_file: Allow skipping checksum calculation for some segments.

[Thiago Jung Bauermann]

Adds checksum argument to kexec_add_buffer specifying whether the given
segment should be part of the checksum calculation.

The next patch will add a way to update segments after a kimage is loaded.
Segments that will be updated in this way should not be checksummed,
otherwise they will cause the purgatory checksum verification to fail
when the machine is rebooted.

As a bonus, we don't need to special-case the purgatory segment anymore
to avoid checksumming it.

Adjust call sites for the new argument.

[RFC][PATCH] arm: ubsan: select ARCH_HAS_UBSAN_SANITIZE_ALL

[Seung-Woo Kim]

To enable UBSAN on arm, this patch enables ARCH_HAS_UBSAN_SANITIZE_ALL
from arm confiuration. Basic kernel booting is tested on arm kernel
enabled CONFIG_UBSAN_SANITIZE_ALL from Exynos5422 based Odroid-XU3
board.

Signed-off-by: Seung-Woo Kim

Because I tested only with specific soc board, so I am not sure the ubsan is
fine for all other cases. So, I send this patch as a RFC.

It's a false positive, a compiler problem.

[PATCH 22/27] [AARCH64] ILP32: support stat syscall family

[Yury Norov]

From: Yury Norov 

stat and statfs structures has their layouts identical to lp64
after changing off_t, ino_t etc sizes to 64-bit. It means we can
pass it to kernel same way as lp64 does.

[PATCH 15/27] [AARCH64] Add support to ldconfig for ILP32 and libilp32

[Yury Norov]

From: Andrew Pinski 

This patch adds support to ldconfig for libilp32 which is used by
ILP32.

* sysdeps/generic/ldconfig.h (FLAG_AARCH64_LIB32): New define.
* elf/cache.c (print_entry): Handle FLAG_AARCH64_LIB32.
* sysdeps/unix/sysv/linux/aarch64/dl-cache.h (_DL_CACHE_DEFAULT_ID):
Define it to be the FLAG_AARCH64_LIB32 if compiling for ILP32.
(add_system_dir): Add libilp32 to the list of system directories.
* sysdeps/unix/sysv/linux/arm/readelflib.c (process_elf_file):
Handle ILP32 elf binaries.

[PATCH 22/27] [AARCH64] ILP32: support stat syscall family

[Yury Norov]

From: Yury Norov 

stat and statfs structures has their layouts identical to lp64
after changing off_t, ino_t etc sizes to 64-bit. It means we can
pass it to kernel same way as lp64 does.

[PATCH 15/27] [AARCH64] Add support to ldconfig for ILP32 and libilp32

[Yury Norov]

From: Andrew Pinski 

This patch adds support to ldconfig for libilp32 which is used by
ILP32.

* elf/cache.c (print_entry): Handle FLAG_AARCH64_LIB32.
* sysdeps/unix/sysv/linux/aarch64/dl-cache.h (_DL_CACHE_DEFAULT_ID):
Define it to be the FLAG_AARCH64_LIB32 if compiling for ILP32.
(add_system_dir): Add libilp32 to the list of system directories.
* sysdeps/unix/sysv/linux/arm/readelflib.c (process_elf_file):
Handle ILP32 elf binaries.

linux-next: Tree for Jun 21

[Stephen Rothwell]

Hi all,

Changes since 20160620:

The net-next tree gained conflicts against the arm-doc tree.

The akpm-current tree gained a conflict against the arm-soc tree.

Non-merge commits (relative to Linus' tree): 4462
 4490 files changed, 203456 insertions(+), 78511 deletions(-)



I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ).  If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one.  You should use "git fetch" and checkout or reset to the new
master.

You can see which trees have been included by looking in the Next/Trees
file in the source.  There are also quilt-import.log and merge.log
files in the Next directory.  Between each merge, the tree was built
with a ppc64_defconfig for powerpc and an allmodconfig (with
CONFIG_BUILD_DOCSRC=n) for x86_64, a multi_v7_defconfig for arm and a
native build of tools/perf. After the final fixups (if any), I do an
x86_64 modules_install followed by builds for x86_64 allnoconfig,
powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
(this fails its final link) and pseries_le_defconfig and i386, sparc
and sparc64 defconfig.

Below is a summary of the state of the merge.

I am currently merging 234 trees (counting Linus' and 34 trees of patches
pending for Linus' tree).

Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next .  If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Randy Dunlap for doing many randconfig builds.  And to Paul
Gortmaker for triage and bug fixes.

Cheers,
Stephen Rothwell

linux-next: Tree for Jun 21

[Stephen Rothwell]

Hi all,

Changes since 20160620:

The net-next tree gained conflicts against the arm-doc tree.

The akpm-current tree gained a conflict against the arm-soc tree.

Non-merge commits (relative to Linus' tree): 4462
 4490 files changed, 203456 insertions(+), 78511 deletions(-)



I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ).  If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one.  You should use "git fetch" and checkout or reset to the new
master.

You can see which trees have been included by looking in the Next/Trees
file in the source.  There are also quilt-import.log and merge.log
files in the Next directory.  Between each merge, the tree was built
with a ppc64_defconfig for powerpc and an allmodconfig (with
CONFIG_BUILD_DOCSRC=n) for x86_64, a multi_v7_defconfig for arm and a
native build of tools/perf. After the final fixups (if any), I do an
x86_64 modules_install followed by builds for x86_64 allnoconfig,
powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
(this fails its final link) and pseries_le_defconfig and i386, sparc
and sparc64 defconfig.

Below is a summary of the state of the merge.

I am currently merging 234 trees (counting Linus' and 34 trees of patches
pending for Linus' tree).

Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next .  If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Randy Dunlap for doing many randconfig builds.  And to Paul
Gortmaker for triage and bug fixes.

Cheers,
Stephen Rothwell

[PATCH 18/27] [AARCH64] Add kernel_sigaction.h for AARCH64 ILP32

[Yury Norov]

From: Andrew Pinski 

In ILP32, the sigaction struct is the same as AARCH64 so we need
the header file kernel_sigaction.h.  To allow for this to work,
we use a long long fields and then add extra casts when converting
between the user exposed struct and the kernel exposed struct.

* sysdeps/unix/sysv/linux/aarch64/kernel_sigaction.h: New file.
* sysdeps/unix/sysv/linux/aarch64/sigaction.c (__libc_sigaction):
Add cast here it is necessary.

[PATCH 20/27] [AARCH64] Make lp64 and ilp32 directories.

[Yury Norov]

From: Andrew Pinski 

The patch makes the ilp32 and lp64 have their own directory under aarch64.
Since ILP32 uses most of the same system calls as LP64 and has a 64bit
off_t, we need make the functions that end in 64 the same as the ones without.
We also need not to special case ioctl or use the already provided mmap.c file.

[PATCH 20/27] [AARCH64] Make lp64 and ilp32 directories.

[Yury Norov]

From: Andrew Pinski 

The patch makes the ilp32 and lp64 have their own directory under aarch64.
Since ILP32 uses most of the same system calls as LP64 and has a 64bit
off_t, we need make the functions that end in 64 the same as the ones without.
We also need not to special case ioctl or use the already provided mmap.c file.

From: Andrew Pinski 

The generic typesizes does not work for ILP32 as the kernel long type
needs to be long long (quad).  time_t, off_t, clock_t, suseconds_t,

[PATCH 12/27] [AARCH64] Add ILP32 support to elf_machine_load_address.

[Yury Norov]

From: Andrew Pinski 

This adds ILP32 support to elf_machine_load_address.
Since elf_machine_load_address depends on the static address being
found without relocations, we need to use 16bit relocation which gets

[PATCH 12/27] [AARCH64] Add ILP32 support to elf_machine_load_address.

[Yury Norov]

From: Andrew Pinski 

This adds ILP32 support to elf_machine_load_address.
Since elf_machine_load_address depends on the static address being
found without relocations, we need to use 16bit relocation which gets
resolved at link time for ILP32.  This is just like how the 32bit
relocation gets resolved at link time for LP64.

[PATCH 0/6] kexec_file: Add buffer hand-over for the next kernel

[Thiago Jung Bauermann]

Hello,

This patch series implements a mechanism which allows the kernel to pass on
a buffer to the kernel that will be kexec'd. This buffer is passed as a
segment which is added to the kimage when it is being prepared by
kexec_file_load.

How the second kernel is informed of this buffer is architecture-specific.
On PowerPC, this is done via the device tree, by checking the properties
/chosen/linux,kexec-handover-buffer-start and
/chosen/linux,kexec-handover-buffer-end, which is analogous to how the
kernel finds the initrd.

This feature was implemented because the Integrity Measurement Architecture
subsystem needs to preserve its measurement list accross the kexec reboot.
This is so that IMA can implement trusted boot support on the OpenPower
platform, because on such systems an intermediary Linux instance running as
part of the firmware is used to boot the target operating system via kexec.
Using this mechanism, IMA on this intermediary instance can hand over to the
target OS the measurements of the components that were used to boot it.

Because there could be additional measurement events between the
kexec_file_load call and the actual reboot, IMA needs a way to update the
buffer with those additional events before rebooting. One can minimize
the interval between the kexec_file_load and the reboot syscalls, but as
small as it can be, there is always the possibility that the measurement
list will be out of date at the time of reboot.

To address this issue, this patch series also introduces kexec_update_segment,
which allows a reboot notifier to change the contents of the image segment
during the reboot process.

There's one patch which makes kimage_load_normal_segment and
kexec_update_segment share code. It's not much code that they can share
though, so I'm not sure if it's worth including this patch.

The last patch is not intended to be merged, it just demonstrates how this
feature can be used.

This series applies on top of v2 of the "kexec_file_load implementation
for PowerPC" patch series at:

[PATCH 21/27] [AARCH64] ILP32: introduce syscalls that pass off_t

[Yury Norov]

From: Yury Norov 

ILP32 has 64-bit off_t, to follow modern requirements.
But kernel clears top-halves of input registers. It means
we have to pass corresponding arguments in a pair, like
aarch32 does. In this patch all affected syscalls are redefined.
Most of them are taken from arm code.

[RFC PATCH 00/27] ARM64: support ILP32

[Yury Norov]

This series enables aarch64 port with ilp32 mode.

After long discussions in kernel list, we finally got
consensus on how ABI should look. This patchset adds
support for the ABI in GLIBC. It is tested with LTP 
with no big regressions comparing to LP64 and AARCH32.

Though it's very raw. Please be patient reviewing it.

ABI details:
 - types are taken from AARCH32, next types turned to 64-bit,
   as modern requirement for new APIs tells:
ino_t  is  u64 type
off_t  is  s64 type
blkcnt_t   is  s64 type
fsblkcnt_t is  u64 type
fsfilcnt_t is  u64 type
 - 64-bit arguments are passed in syscall as register pair,
   as kernel internally clears top halves for all input regs;
 - standard syscall table is used;
 - 32-bit time_t is used. AARCH64/ILP32 is waiting for general
   fix of Y2038 problem just like other 32-bit arches;
 - stat{64}, statfs{64} structures are of the identical layout
   with LP64. Corresponding syscalls are taken from 64-bit code.

[RFC PATCH 00/27] ARM64: support ILP32

[Yury Norov]

This series enables aarch64 port with ilp32 mode.

After long discussions in kernel list, we finally got
consensus on how ABI should look. This patchset adds
support for the ABI in GLIBC. It is tested with LTP 
with no big regressions comparing to LP64 and AARCH32.

Though it's very raw. Please be patient reviewing it.

ABI details:
 - types are taken from AARCH32, next types turned to 64-bit,
   as modern requirement for new APIs tells:
ino_t  is  u64 type
off_t  is  s64 type
blkcnt_t   is  s64 type
fsblkcnt_t is  u64 type
fsfilcnt_t is  u64 type
 - 64-bit arguments are passed in syscall as register pair,
   as kernel internally clears top halves for all input regs;
 - standard syscall table is used;
 - 32-bit time_t is used. AARCH64/ILP32 is waiting for general
   fix of Y2038 problem just like other 32-bit arches;
 - stat{64}, statfs{64} structures are of the identical layout
   with LP64. Corresponding syscalls are taken from 64-bit code.

Really? It's not solution..When send tuning command, it should be returned CRC 
error.
Then it called the dw_mci_stop_dma() and also dma_ops->complete().

When i applied you suggestion, also produced.. :)

[PATCH v20 17/20] perf, tools: Make alias matching case-insensitive

[Sukadev Bhattiprolu]

From: Andi Kleen 

Make alias matching the events parser case-insensitive. This is useful
with the JSON events. perf uses lower case events, but the CPU manuals
generally use upper case event names. The JSON files use lower
case by default too. But if we search case insensitively then
users can cut-n-paste the upper case event names.

So the following works:

% perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true

 Performance counter stats for 'true':

   305  BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL

[PATCH v20 18/20] perf, tools, pmu-events: Fix fixed counters on Intel

[Sukadev Bhattiprolu]

From: Andi Kleen 

The JSON event lists use a different encoding for fixed counters
than perf for instructions and cycles (ref-cycles is ok)

This lead to some common events like inst_retired.any
or cpu_clk_unhalted.thread not counting, when specified with their
JSON name.

Special case these events in the jevents conversion process.
I prefer to not touch the JSON files for this, as it's intended
that standard JSON files can be just dropped into the perf
build without changes.

[PATCH 3/3] staging: lowmemorykiller: select the task with maximum rss to kill

[Ganesh Mahendran]

Current task selecting logic in LMK does not fully aware of the memory
pressure. It may select the task with maximum score adj, but with
least tasksize.

For example, if min_score_adj is 200, and there are 2 tasks in system:
   task a: score adj 500, tasksize 200M
   task b: score adj 1000, tasksize 1M
Current LMK logic will select *task b*. But now the system already have
much memory pressure.

We should select the task with maximum task from all the tasks which
score adj >= min_score_adj.

Overall, we seem to be heading towards the "really weird" territory here.


So the whole commit that Boris bisected down to is weird to me.

Why isn't the temporary text mapping just set up unconditionally in
the temp_level4_pgt?

Why does it have that insane "let's leave the temp_level4_pgt alone
until we actually switch to it, and save away restore_pgd_addr and the
restore_pgd, to then be set up at restore time"?

All the other temporary mappings are set up statically in the
temp_level4_pgt, why not that one?


The text mapping in temp_level4_pgt has to map the image kernel's
physical entry address to the same virtual address that the image
kernel had for it, because the image kernel will switch over to its
own page tables first and it will use its own kernel text mapping from
that point on.  That may not be the same as the text mapping of the
(currently running) restore (or "boot") kernel.

So if we set up the text mapping in temp_level4_pgt upfront, we
basically can't reference the original kernel text (or do any
addressing relative to it) any more after switching over to
temp_level4_pgt.

For some reason I thought that was not doable, but now that I look at
the code it looks like it can be done.  I'll try doing that.


I recalled what the problem was. :-)

In principle, the kernel text mapping in the image kernel may be different
from the kernel text mapping in the restore ("boot") kernel, but the patch
I posted a couple of hours ago actually assumed them to be the same, because
it switched to temp_level4_pgt before jumping to the relocated code.

To get rid of that implicit assumption it has to switch to temp_level4_pgt
from the relocated code itself, but for that to work, the page containing
the relocated code must be executable in the original page tables (it isn't
usually).

So updated patch is appended.

Again, it works for me, but I'm wondering about everybody else.

Thanks,

Subject: [PATCH v2] x86/power/64: Fix kernel text mapping corruption during 
image restoration

Logan Gunthorpe reports that hibernation stopped working reliably for
him after commit ab76f7b4ab23 (x86/mm: Set NX on gap between __ex_table
and rodata).

That turns out to be a consequence of a long-standing issue with the
64-bit image restoration code on x86, which is that the temporary
page tables set up by it to avoid page tables corruption when the
last bits of the image kernel's memory contents are copied into
their original page frames re-use the boot kernel's text mapping,
but that mapping may very well get corrupted just like any other
part of the page tables.  Of course, if that happens, the final
jump to the image kernel's entry point will go to nowhere.

The exact reason why commit ab76f7b4ab23 matters here is that it
sometimes causes a PMD of a large page to be split into PTEs
that are allocated dynamically and get corrupted during image
restoration as described above.

To fix that issue note that the code copying the last bits of the
image kernel's memory contents to the page frames occupied by them
previoulsy doesn't use the kernel text mapping, because it runs from
a special page covered by the identity mapping set up for that code
from scratch.  Hence, the kernel text mapping is only needed before
that code starts to run and then it will only be used just for the
final jump to the image kernel's entry point.

Accordingly, the temporary page tables set up in swsusp_arch_resume()
on x86-64 need to contain the kernel text mapping too.  That mapping
is only going to be used for the final jump to the image kernel, so
it only needs to cover the image kernel's entry point, because the
first thing the image kernel does after getting control back is to
switch over to its own original page tables.  Moreover, the virtual
address of the image kernel's entry point in that mapping has to be
the same as the one mapped by the image kernel's page tables.

With that in mind, modify the x86-64's arch_hibernation_header_save()
and arch_hibernation_header_restore() routines to pass the physical
address of the image kernel's entry point (in addition to its virtual
address) to the boot kernel (a small piece of assembly code involved
in passing the entry point's virtual address to the image kernel is
not necessary any more after that, so drop it).  Update RESTORE_MAGIC
too to reflect the image header format change.

Next, in set_up_temporary_mappings(), use the physical and virtual
addresses of the image kernel's entry point passed in the image
header to set

Overall, we seem to be heading towards the "really weird" territory here.


So the whole commit that Boris bisected down to is weird to me.

Why isn't the temporary text mapping just set up unconditionally in
the temp_level4_pgt?

Why does it have that insane "let's leave the temp_level4_pgt alone
until we actually switch to it, and save away restore_pgd_addr and the
restore_pgd, to then be set up at restore time"?

All the other temporary mappings are set up statically in the
temp_level4_pgt, why not that one?


The text mapping in temp_level4_pgt has to map the image kernel's
physical entry address to the same virtual address that the image
kernel had for it, because the image kernel will switch over to its
own page tables first and it will use its own kernel text mapping from
that point on.  That may not be the same as the text mapping of the
(currently running) restore (or "boot") kernel.

So if we set up the text mapping in temp_level4_pgt upfront, we
basically can't reference the original kernel text (or do any
addressing relative to it) any more after switching over to
temp_level4_pgt.

For some reason I thought that was not doable, but now that I look at
the code it looks like it can be done.  I'll try doing that.


I recalled what the problem was. :-)

In principle, the kernel text mapping in the image kernel may be different
from the kernel text mapping in the restore ("boot") kernel, but the patch
I posted a couple of hours ago actually assumed them to be the same, because
it switched to temp_level4_pgt before jumping to the relocated code.

My concern is that interrupts have *much* more entropy than 1/64th. With a 
revaluation of the assumed entropy in interrupts, we will serve *all* systems 
much better and not just systems with HID.

As said, I think we heavily penalize server type and VM environments against 
desktop systems by crediting entropy in large scale to HID and conversely to a 
much lesser degree to interrupts.

I am not saying that there is an active attack vector. All I want is to 
revalue the entropy in one interrupt which can only be done if we drop the HID 
time stamp collection.

[PATCH 3/5] PM / devfreq: make exynos-bus explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

devfreq/Kconfig:config ARM_EXYNOS_BUS_DEVFREQ
devfreq/Kconfig:bool "ARM EXYNOS Generic Memory Bus DEVFREQ Driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

[PATCH 3/5] PM / devfreq: make exynos-bus explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

devfreq/Kconfig:config ARM_EXYNOS_BUS_DEVFREQ
devfreq/Kconfig:bool "ARM EXYNOS Generic Memory Bus DEVFREQ Driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

[PATCH v4 3/3] mfd: lpc_ich: Add support for Intel Apollo Lake GPIO pinctrl in non-ACPI system

[Tan Jui Nee]

This driver uses the P2SB hide/unhide mechanism cooperatively
to pass the PCI BAR address to the gpio platform driver.

Signed-off-by: Tan Jui Nee 
---
Changes in V4:
- Move Kconfig option CONFIG_X86_INTEL_NON_ACPI from
  [PATCH 2/3] x86/platform/p2sb: New Primary to Sideband bridge support 
driver for Intel SOC's
  to
  [PATCH 3/3] mfd: lpc_ich: Add support for Intel Apollo Lake GPIO 
pinctrl in non-ACPI system
  since the config is used in latter patch.
- Select CONFIG_P2SB when CONFIG_LPC_ICH is enabled.
- Remove #ifdef CONFIG_X86_INTEL_NON_ACPI and use
  #if defined(CONFIG_X86_INTEL_NON_ACPI) when lpc_ich_misc is called
  as suggested by Lee Jones.
- Use single dimensional array instead of 2D array for apl_gpio_io_res
  structure and use DEFINE_RES_IRQ for its IRQ resource.

Changes in V3:
- Simplify register addresses calculation and use DEFINE_RES_MEM_NAMED
  defines for apl_gpio_io_res structure
- Define magic number for P2SB PCI ID
- Replace switch-case with if-else since currently we have only one
  use case
- Only call mfd_add_devices() once for all gpio communities

Changes in V2:
- Add new config option CONFIG_X86_INTEL_NON_ACPI and "select PINCTRL"
  to fix kbuildbot error

What is your concern, specifically?  If it is in the entropy
accounting, there is more entropy in HID event interrupts, so I don't
think adding the extra 1/64th bit of entropy is going to be problematic.

If it is that there are two timestamps that are closely correleated
being added into the pool, the add_interrupt_randomness() path is
going to mix that timestamp with the interrupt timings from 63 other
interrupts before it is mixed into the input pool, while the
add_input_randomness() mixes it directly into the pool.  So if you
think there is a way this could be leveraged into attack, please give
specifics --- but I think we're on pretty solid ground here.

Cheers,

[PATCH 1/5] PM / devfreq: make devfreq explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

menuconfig PM_DEVFREQ
  bool "Generic Dynamic Voltage and Frequency Scaling (DVFS) support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

This code wasn't using module_init, so we don't need to be concerned
with altering the initcall level here.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We don't replace module.h with init.h since the file already has that.
But we do add export.h since this file does export some symbols.

[PATCH 0/5] PM / devfreq: remove modular references from non-modules

[Paul Gortmaker]

For anyone new to the underlying goal of this cleanup, we are trying to
not use module support for code that can never be built as a module since:

 (1) it is easy to accidentally write unused module_exit and remove code
 (2) it can be misleading when reading the source, thinking it can be
 modular when the Makefile and/or Kconfig prohibit it
 (3) it requires the include of the module.h header file which in turn
 includes nearly everything else, thus adding to CPP overhead.
 (4) it gets copied/replicated into other code and spreads like weeds.

We have already merged over 100 of these for mainline to date, so there
is really nothing new to see here, in terms of the type of change.

That said, devfreq changes seen here cover the following categories:

  -just replacement of modular macros with their non-modular
   equivalents that CPP would have inserted anyway

  -the removal of including module.h ; replaced with init.h
   and/or export.h as required based on whether the file used it.

  -the removal of any/all unused/orphaned __exit functions that
   would never be called.

  -the removal of any ".remove" functions that were hooked into
   the driver struct.   This ".remove" function would of
   course not be called from the __exit function since that was
   never run.  However in theory, someone could have triggered it
   via sysfs unbind, even though there isn't a sensible use case
   for doing so.  So to cover that possibility, we've also disabled
   sysfs unbind in the driver.

There are no initcall level changes here; everything stays at the level
of initcall it was previously - either by not using modular versions to
begin with, or by using the builtin level equivalents.

Build tested for arm and arm64 allmodconfig (for which all the drivers
touched here get coverage) on the linux-next tree from today to ensure
no silly typos crept in.

If there is a desire for any of these to be modular, we can definitely
consider that, but by default the changes here keep the code consistent
with existing behaviour.  Thus I do not expand functionality into the
modular realm that I can't run time test, or even know if the modular
instance has a sensible modular use case.

Paul.

What is your concern, specifically?  If it is in the entropy
accounting, there is more entropy in HID event interrupts, so I don't
think adding the extra 1/64th bit of entropy is going to be problematic.

If it is that there are two timestamps that are closely correleated
being added into the pool, the add_interrupt_randomness() path is
going to mix that timestamp with the interrupt timings from 63 other
interrupts before it is mixed into the input pool, while the
add_input_randomness() mixes it directly into the pool.  So if you
think there is a way this could be leveraged into attack, please give
specifics --- but I think we're on pretty solid ground here.

Cheers,

- Ted

[PATCH 1/5] PM / devfreq: make devfreq explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

menuconfig PM_DEVFREQ
  bool "Generic Dynamic Voltage and Frequency Scaling (DVFS) support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

This code wasn't using module_init, so we don't need to be concerned
with altering the initcall level here.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We don't replace module.h with init.h since the file already has that.
But we do add export.h since this file does export some symbols.

[PATCH 0/5] PM / devfreq: remove modular references from non-modules

[Paul Gortmaker]

For anyone new to the underlying goal of this cleanup, we are trying to
not use module support for code that can never be built as a module since:

 (1) it is easy to accidentally write unused module_exit and remove code
 (2) it can be misleading when reading the source, thinking it can be
 modular when the Makefile and/or Kconfig prohibit it
 (3) it requires the include of the module.h header file which in turn
 includes nearly everything else, thus adding to CPP overhead.
 (4) it gets copied/replicated into other code and spreads like weeds.

We have already merged over 100 of these for mainline to date, so there
is really nothing new to see here, in terms of the type of change.

That said, devfreq changes seen here cover the following categories:

  -just replacement of modular macros with their non-modular
   equivalents that CPP would have inserted anyway

  -the removal of including module.h ; replaced with init.h
   and/or export.h as required based on whether the file used it.

  -the removal of any/all unused/orphaned __exit functions that
   would never be called.

  -the removal of any ".remove" functions that were hooked into
   the driver struct.   This ".remove" function would of
   course not be called from the __exit function since that was
   never run.  However in theory, someone could have triggered it
   via sysfs unbind, even though there isn't a sensible use case

[PATCH v4 0/3] pinctrl/broxton: enable platform device in the absent of ACPI enumeration

[Tan Jui Nee]

Hi,
The patches are to cater the need for non-ACPI system whereby
a platform device has to be created in order to bind with
Apollo Lake Pinctrl GPIO platform driver.

The MMIO BAR is accessed over the Primary to Sideband bridge
(P2SB). Since the BIOS prevents the P2SB device from being
enumerated by the PCI subsystem, so we need to hide/unhide P2SB
to lookup the P2SB BAR and pass the PCI BAR address to the gpio
platform driver.

All these three patches have dependencies on each other.

Changes in V4:
- Move Kconfig option CONFIG_X86_INTEL_NON_ACPI from
  [PATCH 2/3] x86/platform/p2sb: New Primary to Sideband bridge support 
driver for Intel SOC's
  to
  [PATCH 3/3] mfd: lpc_ich: Add support for Intel Apollo Lake GPIO 
pinctrl in non-ACPI system
  since the config is used in latter patch.
- Select CONFIG_P2SB when CONFIG_LPC_ICH is enabled.
- Remove #ifdef CONFIG_X86_INTEL_NON_ACPI and use
  #if defined(CONFIG_X86_INTEL_NON_ACPI) when lpc_ich_misc is called
  as suggested by Lee Jones.
- Use single dimensional array instead of 2D array for apl_gpio_io_res
  structure and use DEFINE_RES_IRQ for its IRQ resource.

Changes in V3:
- Simplify register addresses calculation and use DEFINE_RES_MEM_NAMED
  defines for apl_gpio_io_res structure
- Define magic number for P2SB PCI ID
- Replace switch-case with if-else since currently we have only one
  use case
- Only call mfd_add_devices() once for all gpio communities

Changes in V2:
