b61c37f579 lsm_audit: don't specify the audit pre/post callbacks in 'struct common_audit_data'
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.

48c62af68a 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.

3b3b0e4fc1 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.

e37acc0f5e 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
- sprite fix from Jesse"

62fb376e21 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.

The ABI specifies that CR fields CR2--CR4 are nonvolatile across function

leading to CR2--CR4 getting corrupted with guest values, possibly leading

b4e51229d8 KVM: PPC: Book3S HV: Fix kvm_alloc_linear in case where no linears exist
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.

b8e6f8ae51 KVM: PPC: Book3S: Compile fix for ppc32 in HIOR access code
We were failing to compile on book3s_32 with the following errors:

arch/powerpc/kvm/book3s_pr.c:898:79: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

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.

When comparing two pages read from different legs of a mirror, only

In most cases we read a whole page, but in some cases with
bad blocks or odd sizes devices we might read fewer than that.

This bug has been present "forever" but at worst it might cause
a report of two many mismatches and generate a little bit

Because the judgement in function analyse_stripe():

f283d22713 APM: fix deadlock in APM_IOC_SUSPEND ioctl
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.

    separately, do so in f_phonet and cdc_phonet, also from Eric
    Dumazet.

 7) virtio_net accidently uses net_ratelimit() not only on the kernel
    warning but also the statistic bump, fix from Rick Jones.

 8) ip_route_input_mc() uses fixed init_net namespace, oops, use
    dev_net(dev) instead.  Fix from Benjamin LaHaise.

 9) dev_forward_skb() needs to clear the incoming interface index of the
    SKB so that it looks like a new incoming packet, also from Benjamin
    LaHaise.

10) iwlwifi mistakenly initializes a channel entry as 2GHZ instead of
    5GHZ, fix from Stanislav Yakovlev.

11) Missing kmalloc() return value checks in orinoco, from Santosh
    Nayak.

12) ath9k doesn't check for HT capabilities in the right way, it is
    checking ht_supported instead of the ATH9K_HW_CAP_HT flag.  Fix from
    Sujith Manoharan.

13) Fix x86 BPF JIT emission of 16-bit immediate field of AND
    instructions, from Feiran Zhuang.

14) Avoid infinite loop in GARP code when registering sysfs entries.
    From David Ward.

15) rose protocol uses memcpy instead of memcmp in a device address
    comparison, oops.  Fix from Daniel Borkmann.

16) Fix build of lpc_eth due to dev_hw_addr_rancom() interface being
    renamed to eth_hw_addr_random().  From Roland Stigge.

17) Make ipv6 RTM_GETROUTE interpret RTA_IIF attribute the same way
    that ipv4 does.  Fix from Shmulik Ladkani.

18) via-rhine has an inverted bit test, causing suspend/resume
    regressions.  Fix from Andreas Mohr.

19) RIONET assumes 4K page size, fix from Akinobu Mita.

20) Initialization of imask register in sky2 is buggy, because bits are
    "or'd" into an uninitialized local variable.  Fix from Lino
    Sanfilippo.

21) Fix FCOE checksum offload handling, from Yi Zou.

22) Fix VLAN processing regression in e1000, from Jiri Pirko.

f68c56b7d2 firewire: restore the device.h include in linux/firewire.h
Commit 313162d0b8 ("device.h: audit and cleanup users in main include
dir") exchanged an include <linux/device.h> for a struct *device but in
actuality I misread this file when creating 313162d and it should have
remained an include.

There were no build regressions since all consumers were already getting
device.h anyway, but make it right regardless.

Commit b4816afa39 ("Move the asm-generic/system.h xchg()

asm/cmpxchg.h but the parisc arch never got one.  Fork the cmpxchg

Some minor whitespace fixups were done on the block of code that created
the new file.

3d92e05118 avr32: fix build failures from mis-naming of atmel_nand.h
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:
  arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory
  In file included from arch/avr32/boards/atstk1000/setup.c:22:

  make[2]: *** [arch/avr32/boards/atstk1000/setup.o] Error 1

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.
