This patch add support for livepatch on arm64 based on the gcc -mfentry
feature and the ftrace DYNAMIC_FTRACE_WITH_REGS feature.

If ftrace_ops is registered with flag FTRACE_OPS_FL_SAVE_REGS, the
arch that support DYNAMIC_FTRACE_WITH_REGS will pass a full set of
pt_regs to the ftrace_ops callback function, which may read or change
the value of the pt_regs and the pt_regs will be restored to support
work flow redirection
This patch depends on the compiler's mfentry feature for arm64 that
proposed by this patchset. If the kernel is compiled with this feature,
the entry of each function like:
foo:
mov x9, x30
bl __fentry__
mov x30, x9
When -mfentry is used, the call is to '__fentry__' and not
The function of ftrace_function_stub_ip is to convert the function
address to the ftrace stub calling instruction address.
This is needed for the platform that the complier does not support
"profile before prologue" feature and the profile calling instruction
is not at begin of the function.

The wilc1000 driver uses definitions such as DEBUG_LEVEL, DEBUG,
and PRINT_INFO. This causes compile errors on S390 which has similar
definitions in its core code. Disable the driver for S390 instead
of giving the non-standard messaging code credit by trying to fix it.

This patch fixes to call f2fs_inherit_context twice for newly created symlink.
The original one is called by f2fs_add_link(), which invokes f2fs_setxattr.
If the second one is called again, f2fs_setxattr is triggered again with same
encryption index.

Skylake moved to 32 Last Branch Records, from previously 16.
The current call stack LBR implementation reads all LBRs and
also saves/restores them on context switch. This patchkit
adds some optimizations to avoid
From: Andi Kleen
With PEBSv3 the PEBS record contains a time stamp. That means we can allow
free-running PEBS without a PMI even if the user program requested a time stamp.
This avoids the need to use -T to get free running PEBS, and also avoids
any problems with mis-identifying MMAPs later.
From: Andi Kleen
Automatically disable collecting branch flags and cycles with
--call-graph lbr. This allows avoiding a bunch of extra MSR
reads in the PMI on Skylake.
When the kernel doesn't support the new flags they are automatically
cleared in the fallback code.
Signed-off-by: Andi Kleen
From: Andi Kleen
With LBRv5 reading the extra LBR flags like mispredict, TSX, cycles
is not free anymore, as it has moved to a separate MSR.
For callstack mode we don't need any of this information; so we can
avoid the unnecessary MSR read. Add flags to the perf interface

From: Andi Kleen
Use the correct index to save/restore the LBR_INFO_x MSR in
callstack mode. This is more a cleanup, as even with the wrong
index the register was correctly saved/restored, and also
LBR callgraph mode in perf tools do not really need anything in
LBR_INFO. But still better to use
From: Andi Kleen
In callstack mode the LBR is not a ring buffer, but a stack that grows up
and down. This means in this case we don't need to access all LBRs, only the
ones up to TOS. Do this optimization for the normal LBR read, and the context

Lets only post patches people can apply, it makes it harder to figure
out stuff. I'll take a look at the patches, but it would be good to
get them
The CrystalCove GPIO irqchip doesn't have irq_set_wake callback defined
so we should set IRQCHIP_SKIP_SET_WAKE for it or it would cause an irq
desc's wake_depth unbalanced warning during system resume phase from the
gpio_keys driver, which is the driver for the power button of the ASUS

Create and maintain struct machines in struct perf_tool and pass it to
struct perf_session. This is a preparation of sharing machines among
sessions in case of multi-thread report.

With multi-thread report, separate sessions can be passed to each
thread, in this case we should keep a single machine state for all
struct sessions. Separate machines and have a pointer in sessions.

Hi Arnaldo,
This is what I have now for the earlier discussion [1]. I just used
machines__new/delete functions directly whenever a session is
created/deleted. As it touches many callsites, and it needs bit more
caring about the error path, you may want to split the first patch for
each command.

Hi Keith,
I'm getting lockdep warning around use of ext_devt_lock.
[11428.266019] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.
As you say in
2da78092dda1 ("block: Fix dev_t minor allocation lifetime")
ext_devt_lock can be taken from call_rcu's soft-irq.
I think that means it
Hi Linus,
A well intentioned switch to the DEVICE_ATTR_* macros changed the sys

By 'make build-test' a warning is found in probe-event.c that, after
commit 419e873828 (perf probe: Show the error reason comes from
invalid DSO) the only user of kernel_get_module_dso() is
open_debuginfo(). Which is not compiled if HAVE_DWARF_SUPPORT not set.
'make build-test' found this problem
