Pull drm update from Dave Airlie:
"This pull just contains a forward of the Intel fixes from Daniel.
The only annoyance is the RC6 enable, which really should have made
-next, but since Ubuntu are shipping it I reckon its getting a good
testing now by the time 3.4 comes out.
The pull from Daniel contains his pull message to me:
"A few patches for 3.4, major part is 3 regression fixes:
- ppgtt broke hibernate on snb/ivb. Somehow our QA claims that it
still works, which is why this has not been caught earlier.
- ppgtt flails in combination with dmar. I kinda expected this one :(
- fence handling bugfix for gen2/3. Iirc this one is about a year
old, fix curtesy Chris Wilson. I've created an shockingly simple
i-g-t test to catch this in the future."
Wrt regressions I've just got a report that gmbus (newly enabled
again in 3.4) is a bit noisy. I'm looking into this atm.
Also included are the rc6 enable patches for snb from Eugeni. I
wanted to include these in the main 3.4 pull but screwed it up.
Please hit me. Imo these kind of patches really should go in
before -rc1, but in thise case rc6 has brought us tons of press and
guinea pigs^W^W testers and ubuntu is already running with it. So
I estimate a pretty small chance for this to blow up.
And some smaller things:
- two minor locking snafus
- server gt2 ivb pciid
- 2 patches to sanitize the register state left behind by the bios
some more
- 2 new quirk entries
- cs readback trick against missed IRQs from ivb also enabled on snb
- sprite fix from Jesse"
Let's see if the "enable RC6 on sandybridge" finally works and sticks.
I've been enabling it by hand (i915.i915_enable_rc6=1) for several
months on my Macbook Air, and it definitely makes a difference (and has
worked for me). But every time we enabled it before it showed some odd
hw buglet for *somebody*.
This time it's all good, I'm sure.

It just bloats the audit data structure for no good reason, since the
only time those fields are filled are just before calling the
common_lsm_audit() function, which is also the only user of those
fields.
So just make them be the arguments to common_lsm_audit(), rather than
bloating that structure that is passed around everywhere, and is
initialized in hot paths.

After shrinking the common_audit_data stack usage for private LSM data I'm
not going to shrink the data union. To do this I'm going to move anything
larger than 2 void * ptrs to it's own structure and require it to be declared
separately on the calling stack. Thus hot paths which don't need more than
a couple pointer don't have to declare space to hold large unneeded
structures. I could get this down to one void * by dealing with the key
struct and the struct path. We'll see if that is helpful after taking care of
networking.

Linus found that the gigantic size of the common audit data caused a big
perf hit on something as simple as running stat() in a loop. This patch
requires LSMs to declare the LSM specific portion separately rather than
doing it in a union. Thus each LSM can be responsible for shrinking their
portion and don't have to pay a penalty just because other LSMs have a
bigger space requirement.

mplayer -vo fbdev tries to create a screen that is twice as tall as the
allocated framebuffer for "doublebuffering". By default, and all in-tree
users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer
originally allocated.

In kvm_alloc_linear we were using and deferencing ri after the
list_for_each_entry had come to the end of the list. In that
situation, ri is not really defined and probably points to the
list head. This will happen every time if the free_linears list
is empty, for instance. This led to a NULL pointer dereference
crash in memset on POWER7 while trying to allocate an HPT in the
case where no HPTs were preallocated.
This fixes it by using a separate variable for the return value
from the loop iterator.

Fix this by explicity casting the u64 to long before we use it as a pointer.
Also, on PPC32 we can not use get_user/put_user for 64bit wide variables,
as there is no single instruction that could load or store variables that big.
So instead, we have to use copy_from/to_user which works everywhere.

I found the Xorg server on my ARM device stuck in the 'msleep()' loop
in apm_ioctl.
I suspect it had attempted suspend immediately after resuming and lost
a race.
During that msleep(10);, a new suspend cycle must have started and
changed ->suspend_state to SUSPEND_PENDING, so it was never seen to
be SUSPEND_DONE and the loop could never exited. It would have moved on
to SUSPEND_ACKTO but never been able to reach SUSPEND_DONE.
So change the loop to only run while SUSPEND_ACKED rather than until
SUSPEND_DONE. This is much safer.

Commit b4816afa39 ("Move the asm-generic/system.h xchg()
implementation to asm-generic/cmpxchg.h") introduced the concept of
asm/cmpxchg.h but the parisc arch never got one. Fork the cmpxchg
content out of the asm/atomic.h file to create one.
Some minor whitespace fixups were done on the block of code that created
the new file.

Commit 3bed8d6746 ("Disintegrate asm/system.h for Blackfin [ver #2]")
introduced arch/blackfin/include/asm/cmpxchg.h but has it also including
the asm-generic one which causes this:

It really only needs two simple defines from asm-generic, so just use
those instead.

Commit bf4289cba0 ("ATMEL: fix nand ecc support") indicated that it
wanted to "Move platform data to a common header
include/linux/platform_data/atmel_nand.h" and the new header even had
re-include protectors with:
#ifndef __ATMEL_NAND_H__
However, the file that was added was simply called atmel.h
and this caused avr32 defconfig to fail with:
In file included from arch/avr32/boards/atstk1000/setup.c:22:

It seems the scope of the file contents will expand beyond
just nand, so ignore the original intention, and fix up the
users who reference the bad name with the _nand suffix.

Commit dae2e9f430 changed dev_alloc_skb()
to netdev_alloc_skb(), adding a dev pointer, but erroneously used "->"
instead of "." for a struct member when accessing the dev pointer.
This change fixes the build breakage.

Pull HSI (High Speed Synchronous Serial Interface) framework from Carlos Chinea:
"The High Speed Synchronous Serial Interface (HSI) is a serial
interface mainly used for connecting application engines (APE) with
cellular modem engines (CMT) in cellular handsets.
The framework is currently being used for some people and we would
like to see it integrated into the kernel for 3.3. There is no HW
controller drivers in this pull, but some people have already some of
them pending which they would like to push as soon as this integrated.
I am also working on the acceptance for an TI OMAP one, based on a
compatible legacy version of the interface called SSI."
Ok, so it didn't get into 3.3, but here it is pulled into 3.4.
Several people piped up to say "yeah, we want this".
