Only run vtime_user_enter, vtime_user_exit, and the user enter & exit
trace points when we are entering or exiting user state, respectively.
The RCU code only distinguishes between "idle" and "not idle or kernel".
There should be no need to add an additional (unused) state
From: Rik van Riel
Export context_tracking_user_enter/exit so it can be used by KVM.

Add the expected ctx_state as a parameter to context_tracking_user_enter

When running a KVM guest on a system with NOHZ_FULL enabled, and the
KVM guest running with idle=poll mode, we still get wakeups of the
rcuos/N threads.
This problem has already been solved for user space by telling the
RCU subsystem that the CPU is in an extended quiescent state while

This makes no sense. How can a master device manage a slave device?

Since tracefs will now hold the event directory for perf, and
even though by default, debugfs still mounts tracefs on the
debugfs/tracing directory, the system admin may now choose to not
mount debugfs and instead just mount tracefs instead.
Having tracefs
From: "Steven Rostedt (Red Hat)"
In preparation for adding tracefs for perf to use, create a findfs
helper utility that find_debugfs uses instead of hard coding the search
in the code. This will allow for a find_tracefs to be used as well.

As I'm trying to move the tracing directory from debugfs, perf needs to
be aware of this as system admins will now be able to mount the tracing
directory without needing to mount debugfs. This patch series addresses
this and makes perf aware of tracefs.
You can also get this series from my repo

It's rather strange to be checking the debugfs MAGIC number for the
tracing directory. A system admin may want to have a custom set of events
to trace and it should be allowed to let the admin make a temp file
(even for tracing virtual boxes, this is useful).
From: "Steven Rostedt (Red Hat)"
As tracefs may be mounted instead of debugfs to get to the event directories,
have perf know about tracefs, and use that file system over debugfs if it
is present.

When using PCI_PROBE_ONLY, Linux does not assign resource to PCI devices.
This causes error when calling the pci_enable_resources function, and not
allowing driver to set the PCI_COMMAND_IO and PCI_COMMAND_MEMORY flag in
the config space of endpoint device since it checks if the resource parent

This patch series modifies the current PCI generic host controller

Replacing pci_common_init_dev with pci_scan_root_bus, and remove reference
to struct pci_sys_data and pci_hw, which is specific to ARM32. This allows

When the SSC acts as BCK master, use a ratnum rule to limit
the rate instead of only doing the standard rates. When the SSC
acts as BCK slave, allow any BCK frequency up to the SSC master
clock, divided by either of 2, 3 or 6.
Put a cap at 384kHz. Who's /ever/ going to need
, rename the variable, as suggested by Wolfram Sang
.

Add maudio power domain to Exynos 5420 DTSI file so its state could be
tracked. This actually won't power down this domain because the pl330
dmaengine driver (for adma channel) uses IRQ safe runtime PM. Thus the
patch should not introduce any functional change except of visibility of
this domain
This introduces a module parameter to detect zero writes and not to
allocate memory. Read requests for unallocated (unwritten) region
end up by reading zero. So this can save zeroed memory consumption
with extra overhead for the detection.
This feature is useful for testing filesystems and user
The problem here is that we check:
if (dev >= SNDRV_CARDS)
Then we increment "dev".
if (!joystick_port[dev++])
Then we use it as an offset into a array with SNDRV_CARDS elements.
if (!request_region(joystick_port[dev], 8, "Riptide gameport")) {
This has 3 effects:
1)

Cfq_lookup_create_cfqg() allocates struct blkcg_gq using GFP_ATOMIC.
In cfq_find_alloc_queue() possible allocation failure is not handled.
As a result kernel oopses on NULL pointer dereference when
cfq_link_cfqq_cfqg() calls cfqg_get() for NULL pointer.

The delay time for wait the 24MHz OSC stabilization is 750ms, and the
delay time for wait the external PMU stabilization is 750ms too, let's
decrease them to 30ms.

The watchdog clock should be disable in dw_wdt_suspend, but we set a
dummy clock to watchdog for rk3288. So the watchdog will continue to
work during suspend. And we switch the system clock to 32khz from 24Mhz,
during suspend, so the watchdog timer over count will increase to
755 times, about 12.5

Hello, Linus.
Mostly driver-specific changes. Nothing too noteworthy. This pull
request contains three merges from for-3.19-fixes. The first two are
to pull ahci_xgene and sata_dwc_460ex fix commits which are depended
upon by later changes. The last one is to pull in a fix patch which
missed

Hi All,
Please review this patch.
this patch is aimed to solve some indentation issue. It has also solved
three trivial error in efifb.c file.
And I have also changed printk with pr_err, pr_info ... at respective places.

x86 kprobes is unable to probe at 2 bytes nop like:

Such nops have exactly 5 bytes which is able to hold a relative jmp

Hello, Linus.
Three mostly trivial patches. The biggest change is that blkio is now
initialized before memcg which will be needed to make memcg and blkcg
cooperate on writeback IOs.
Thanks.
