Pull DMA mapping branch from Marek Szyprowski:
"Short summary for the whole series:
A few limitations have been identified in the current dma-mapping
design and its implementations for various architectures. There exist
more than one function for allocating and freeing the buffers:
currently these 3 are used dma_{alloc, free}_coherent,
dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.
For most of the systems these calls are almost equivalent and can be
interchanged. For others, especially the truly non-coherent ones
(like ARM), the difference can be easily noticed in overall driver
performance. Sadly not all architectures provide implementations for
all of them, so the drivers might need to be adapted and cannot be
easily shared between different architectures. The provided patches
unify all these functions and hide the differences under the already
existing dma attributes concept. The thread with more references is
available here:
http://www.spinics.net/lists/linux-sh/msg09777.html
These patches are also a prerequisite for unifying DMA-mapping
implementation on ARM architecture with the common one provided by
dma_map_ops structure and extending it with IOMMU support. More
information is available in the following thread:
http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819
More works on dma-mapping framework are planned, especially in the
area of buffer sharing and managing the shared mappings (together with
the recently introduced dma_buf interface: commit
d15bd7ee445d
"dma-buf: Introduce dma buffer sharing mechanism").
The patches in the current set introduce a new alloc/free methods
(with support for memory attributes) in dma_map_ops structure, which
will later replace dma_alloc_coherent and dma_alloc_writecombine
functions."
People finally started piping up with support for merging this, so I'm
merging it as the last of the pending stuff from the merge window.
Looks like pohmelfs is going to wait for 3.5 and more external support
for merging.

Merge branch 'selinux' ("struct common_audit_data" sanitizer)
Merge common_audit_data cleanup patches from Eric Paris.
This is really too late, but it's a long-overdue cleanup of the costly
wrapper functions for the security layer.
The "struct common_audit_data" is used all over in critical paths,
allocated and initialized on the stack. And used to be much too large,
causing not only unnecessarily big stack frames but the clearing of the
(mostly useless) data was also very visible in profiles.
As a particular example, in one microbenchmark for just doing "stat()"
over files a lot, selinux_inode_permission() used 7% of the CPU time.
That's despite the fact that it doesn't actually *do* anything: it is
just a helper wrapper function in the selinux security layer.
This patch-series shrinks "struct common_audit_data" sufficiently that
code generation for these kinds of wrapper functions is improved
noticeably, and we spend much less time just initializing data that we
will never use.
The functions still get called all the time, and it still shows up at
3.5+% in my microbenchmark, but it's quite a bit lower down the list,
and much less noticeable.

LSM: shrink the common_audit_data data union
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.

LSM: shrink sizeof LSM specific portion of common_audit_data
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.

Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-intel-fixes
From Daniel Vetter:
"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

drm: Validate requested virtual size against allocated fb size
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.

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.

irq_work: fix compile failure on MIPS from system.h split
Builds of the MIPS platform ip32_defconfig fails as of commit
0195c00244dc ("Merge tag 'split-asm_system_h ...") because MIPS xchg()
macro uses BUILD_BUG_ON and it was moved in commit
b81947c646bf
("Disintegrate asm/system.h for MIPS").
The root cause is that the system.h split wasn't tested on a baseline
with commit
6c03438edeb5 ("kernel.h: doesn't explicitly use bug.h, so
don't include it.")
Since this file uses BUG code in several other places besides the xchg
call, simply make the inclusion explicit.

The code tries various methods for retreiving the BIOS data. However
it doesn't clear the bios->data pointer between the iterations.
In some cases, the shadow() method will fail and not update bios->data
at all, which will cause us to "score" the old data and incorrectly
attribute that score to the new method. This can cause double frees
later when disposing of the unused data.
Additionally, we were not freeing the data for methods that fail the
score test (we only freed when a "best" is superseeded, not when the
new method has a lower score than the exising "best"). Fix that as well.

ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE
message, then a route is searched as if a packet was received on the
specified 'iif' interface.
However in IPv6, RTA_IIF is not interpreted in the same way:
'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the
RTA_IIF attribute.
As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look
for a route as if a packet was received on a specific interface.
Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a

net: lpc_eth: Fix rename of dev_hw_addr_random
In parallel to the integration of lpc_eth.c, dev_hw_addr_random() has been
renamed to eth_hw_addr_random(). This patch fixes it also in the new driver
lpc_eth.c.

net/netfilter/nfnetlink_acct.c: use linux/atomic.h

rose_dev: fix memcpy-bug in rose_set_mac_address
If both addresses equal, nothing needs to be done. If the device is down,
then we simply copy the new address to dev->dev_addr. If the device is up,
then we add another loopback device with the new address, and if that does
not fail, we remove the loopback device with the old address. And only
then, we update the dev->dev_addr.

net/garp: avoid infinite loop if attribute already exists
An infinite loop occurred if garp_attr_create was called with the values
of an existing attribute. This might happen if a previous leave request
for the attribute has not yet been followed by a PDU transmission (or,
if the application previously issued a join request for the attribute
and is now issuing another one, without having issued a leave request).
If garp_attr_create finds an existing attribute having the same values,
return the address to it. Its state will then get updated (i.e., if it
was in a leaving state, it will move into a non-leaving state and not
get deleted during the next PDU transmission).
To accomplish this fix, collapse garp_attr_insert into garp_attr_create
(which is its only caller).

CIFS: Fix VFS lock usage for oplocked files
We can deadlock if we have a write oplock and two processes
use the same file handle. In this case the first process can't
unlock its lock if the second process blocked on the lock in the
same time.
Fix it by using posix_lock_file rather than posix_lock_file_wait
under cinode->lock_mutex. If we request a blocking lock and
posix_lock_file indicates that there is another lock that prevents
us, wait untill that lock is released and restart our call.
