The goal of this set of patches is to change vm86 support to return to
userspace with the normal exit paths instead of leaving data on the kernel
stack and jumping directly into the exit asm routines. This fixes issues
like ptrace and syscall auditing not working with vm86, and makes possible

We have call_rcu_func_t for a quite while, but we still use explicit
function pointer type equivalents in some places, this patch replace
these equivalent types with call_rcu_func_t to gain better readability.

As we now have rcu_callback_t typedefs as the type of rcu callbacks, we
should use it in call_rcu*() and friends as the type of parameters. This
could save us a few lines of code and make it clear which function
requires an rcu callbacks rather than other callbacks as its argument.
Besides, this
Commit ("rcu: Create a synchronize_rcu_mult()") in linux-rcu.git#rcu/next
branch has introduced rcu_callback_t as the type for rcu callback
functions and call_rcu_func_t has been introduced for a while. This patch
series uses the rcu_callback_t and call_rcu_func_t to save a few lines of
code.

This patch provides Intel PT logging feature. When system boots with a
parameter "intel_pt_log", log buffers for Intel PT are allocated and
logging starts, then processor flow information is written in the log
buffer by hardware like flight recorder. This is very helpful to

Hi all,
These patch series provide logging feature for Intel Processor Trace
(Intel PT).
Intel PT is a new feature of Intel CPU "Broadwell", it captures
information about program execution flow. Here is a article about Intel
PT.

Antoine and Rob,
I was just doing some testing with USB on a Qualcomm SoC.
I followed the instructions in the binding document:
Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt
which has a compatible for "qcom,ci-hdrc", and is, in general,
for chipidea-based USB controllers.
It says in
The kernel's NMI watchdog has nothing to do with the watchdog
subsystem. Its header declarations are in linux/nmi.h, not in
linux/watchdog.h.
The code provided two sets of dummy functions if HARDLOCKUP_DETECTOR
is not configured, one in the include file and one in kernel/watchdog.c.

That bit's fine. The weird bit is:

Since that's putting the arch-independent format into the pg_prot.
Oops, missed that. Yeah that's funky.

Hi Linus,
Here are the outstanding target-pending fixes for v4.2-rc5 code.
Please go ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master
This series is larger than what I'd normally be conformable with sending
for a -rc5 PULL request..
However,

The recover_policy is unsed in cpufreq_online() to indicate whether
a new policy object is created or an existing one is reinitialized.
The "recover" part of the name is slightly confusing (it should be
"reinitialization" rather than "recovery") and the logical not (!)

To separate the CPU online interface from the CPU device
registration, split cpufreq_online() out of cpufreq_add_dev()
and make cpufreq_cpu_callback() call the former, while
cpufreq_add_dev() itself will only be used as the CPU device
addition subsystem interface
