Paul Mackerras cd74c86bdf perf_counter, powerpc, sparc: Fix compilation after perf_counter_overflow() change
Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow
handling") removed the regs field from struct perf_sample_data and
added a regs parameter to perf_counter_overflow().  This breaks the
build on powerpc (and Sparc) as reported by Sachin Sant:

  arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
  arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializer

This adjusts arch/powerpc/kernel/perf_counter.c to correspond with the
new struct perf_sample_data and perf_counter_overflow().

[ v2: also fix Sparc, Markus Metzger <markus.t.metzger@intel.com> ]

Linus Torvalds dcbb5593d9 loongson: fix cut-and-paste mis-merge
Ingo points out that I screwed up when merging the 'timers-for-linus'
branch in commit a03fdb7612.

A bit too much copy-and-pasting caused the end result to have an
extraneous 'return' in the middle of an expression.  That was obviously
bogus.  Blush.

Alok Kataria 6399c08745 x86: Print the hypervisor returned tsc_khz during boot
On an AMD-64 system the processor frequency that is printed during
system boot, may be different than the tsc frequency that was
returned by the hypervisor, due to the value returned from
calibrate_cpu.

For debugging timekeeping or other related issues it might be
better to get the tsc_khz value returned by the hypervisor.

The patch below now prints the tsc frequency that the VMware
hypervisor returned.

This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.

This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

Arjan van de Ven 288f023e70 tracing, x86, cpuidle: Move the end point of a C state in the power tracer
The "end of a C state" trace point currently happens before
the code runs that corrects the TSC for having stopped during idle.

The result of this is that the timestamp of the end-of-C-state event
is garbage on cpus where the TSC stops during idle.

This patch moves the end point of the C state to after the timekeeping
engine of the kernel has been corrected.

On Intel platforms, we can use logical flat mode if there are <= 8

Guennadi Liakhovetski 0bab829de1 V4L/DVB (12509): sh: prepare board-ap325rxa.c for v4l2-subdev conversion
We will be registering and unregistering the soc_camera_platform platform
device multiple times, therefore we need a .release() method and have to
nullify the kobj.

soc_camera_platform.c is only used by y SuperH ap325rxa board. This patch
converts soc_camera_platform.c and its users for the soc-camera platform-
device conversion and also extends soc-camera core to handle non-I2C cameras.

Nelson Elhage 9c88b25bcf frv: clean up linker script using new linker script macros.
This is largely a straightforward conversion. The patch results in
fewer output sections, and some data being reordered, but should have
no functional impact.

Also, note that this patch moves some data (namely, init_task and
cacheline-aligned) inside [_sdata,_edata].

Because frv already builds using -ffunction-sections -fdata-sections,
we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not
currently include the required .bss.* and .data.* sections.

It appears that frv copied the .altinstructions definitions in its linker
script from x86. Since frv doesn't put anything in those sections, this
is just dead code.

Markus Metzger 5622f295b5 x86, perf_counter, bts: Optimize BTS overflow handling
Draining the BTS buffer on a buffer overflow interrupt takes too
long resulting in a kernel lockup when tracing the kernel.

Restructure perf_counter sampling into sample creation and sample
output.

Prepare a single reference sample for BTS sampling and update the
from and to address fields when draining the BTS buffer. Drain the
entire BTS buffer between a single perf_output_begin() /
perf_output_end() pair.
