Pull powerpc updates from Benjamin Herrenschmidt:
"Here are the powerpc goodies for 3.5. Main highlights are:
- Support for the NX crypto engine in Power7+
- A bunch of Anton goodness, including some micro optimization of our
syscall entry on Power7
- I converted a pile of our thermal control drivers to the new i2c
APIs (essentially turning the old therm_pm72 into a proper set of
windfarm drivers). That's one more step toward removing the
deprecated i2c APIs, there's still a few drivers to fix, but we are
getting close
- kexec/kdump support for 47x embedded cores
The big missing thing here is no updates from Freescale. Not sure
what's up here, but with Kumar not working for them anymore things are
a bit in a state of flux in that area."

This reverts commit cb04ff9ac4 ("sched, perf: Use a single
callback into the scheduler").
Before this change was introduced, the process switch worked
like this (wrt. to perf event schedule):
schedule (prev, next)
- schedule out all perf events for prev
- switch to next
- schedule in all perf events for current (next)
After the commit, the process switch looks like:
schedule (prev, next)
- schedule out all perf events for prev
- schedule in all perf events for (next)
- switch to next
The problem is, that after we schedule perf events in, the pmu
is enabled and we can receive events even before we make the
switch to next - so "current" still being prev process (event
SAMPLE data are filled based on the value of the "current"
process).
Thats exactly what we see for test__PERF_RECORD test. We receive
SAMPLES with PID of the process that our tracee is scheduled
from.
Discussed with Peter Zijlstra:
> Bah!, yeah I guess reverting is the right thing for now. Sad
> though.
>
> So by having the two hooks we have a black-spot between them
> where we receive no events at all, this black-spot covers the
> hand-over of current and we thus don't receive the 'wrong'
> events.
>
> I rather liked we could do away with both that black-spot and
> clean up the code a little, but apparently people rely on it.

The SCH311x chip contains 2 watchdogs. One is the watchdog programmable
by the runtime register at address 0x65-0x68, the other is the watchdog
inside the power on reset generator. This second watchdog has a fixed
timeout value of ~1.6 seconds and is configurable only by the RESGEN
register.
The BIOS normally takes care of the RESGEN watchdog and disables it (at
least) before the OS is booted.
Unfortunately the sch311x_wdt driver clears bit 0 of the RESGEN register
which has the effect that at the latest 1.6 seconds later, a POR is
triggered.
The attached patch fixes this problem by completely removing any
reference to the RESGEN watchdog from the sch311x_wdt driver.

This adds handle->fd and fd->handle support to i915, this is to allow
for offloading of rendering in one direction and outputs in the other.
v2 from Daniel Vetter:
- fixup conflicts with the prepare/finish gtt prep work.
- implement ppgtt binding support.
Note that we have squat i-g-t testcoverage for any of the lifetime and
access rules dma_buf/prime support brings along. And there are quite a
few intricate situations here.
Also note that the integration with the existing code is a bit
hackish, especially around get_gtt_pages and put_gtt_pages. It imo
would be easier with the prep code from Chris Wilson's unbound series,
but that is for 3.6.
Also note that I didn't bother to put the new prepare/finish gtt hooks
to good use by moving the dma_buf_map/unmap_attachment calls in there
(like we've originally planned for).
Last but not least this patch is only compile-tested, but I've changed
very little compared to Dave Airlie's version. So there's a decent
chance v2 on drm-next works as well as v1 on 3.4-rc.
v3: Right when I've hit sent I've noticed that I've screwed up one
obj->sg_list (for dmar support) and obj->sg_table (for prime support)
disdinction. We should be able to merge these 2 paths, but that's
material for another patch.

This set includes some minor fixes and improvements.
The one large patch addresses the special "nodir" mode,
which has been a long neglected proof of concept, but
with these fixes seems to be quite usable. It allows
the resource master to be assigned statically instead of
dynamically, which can improve performance if there is
little locality and most resources are shared.

Pull scheduler changes from Ingo Molnar:
"The biggest change is the cleanup/simplification of the load-balancer:
instead of the current practice of architectures twiddling scheduler
internal data structures and providing the scheduler domains in
colorfully inconsistent ways, we now have generic scheduler code in
kernel/sched/core.c:sched_init_numa() that looks at the architecture's
node_distance() parameters and (while not fully trusting it) deducts a
NUMA topology from it.
This inevitably changes balancing behavior - hopefully for the better.
There are various smaller optimizations, cleanups and fixlets as well"

Pull perf changes from Ingo Molnar:
"Lots of changes:
- (much) improved assembly annotation support in perf report, with
jump visualization, searching, navigation, visual output
improvements and more.
- kernel support for AMD IBS PMU hardware features. Notably 'perf
record -e cycles:p' and 'perf top -e cycles:p' should work without
skid now, like PEBS does on the Intel side, because it takes
advantage of IBS transparently.
- the libtracevents library: it is the first step towards unifying
tracing tooling and perf, and it also gives a tracing library for
external tools like powertop to rely on.
- infrastructure: various improvements and refactoring of the UI
modules and related code
- infrastructure: cleanup and simplification of the profiling
targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)
- tons of robustness fixes all around
- various ftrace updates: speedups, cleanups, robustness
improvements.
- typing 'make' in tools/ will now give you a menu of projects to
build and a short help text to explain what each does.
- ... and lots of other changes I forgot to list.
The perf record make bzImage + perf report regression you reported
should be fixed."

Pull cgroup updates from Tejun Heo:
"cgroup file type addition / removal is updated so that file types are
added and removed instead of individual files so that dynamic file
type addition / removal can be implemented by cgroup and used by
controllers. blkio controller changes which will come through block
tree are dependent on this. Other changes include res_counter cleanup
and disallowing kthread / PF_THREAD_BOUND threads to be attached to
non-root cgroups.
There's a reported bug with the file type addition / removal handling
which can lead to oops on cgroup umount. The issue is being looked
into. It shouldn't cause problems for most setups and isn't a
security concern."

Commit d065bd810b
(mm: retry page fault when blocking on disk transfer) and
commit 37b23e0525
(x86,mm: make pagefault killable)
The above commits introduced changes into the x86 pagefault handler
for making the page fault handler retryable as well as killable.
These changes reduce the mmap_sem hold time, which is crucial
during OOM killer invocation.
Port these changes to hexagon.
