b1a808ff43 Merge branch 'for-next' of git://gitorious.org/kernel-hsi/kernel-hsi
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".

83e3fa6f01 irq_work: fix compile failure on MIPS from system.h split
Builds of the MIPS platform ip32_defconfig fails as of commit
0195c00244 ("Merge tag 'split-asm_system_h ...") because MIPS xchg()
macro uses BUILD_BUG_ON and it was moved in commit b81947c646
("Disintegrate asm/system.h for MIPS").

The root cause is that the system.h split wasn't tested on a baseline
with commit 6c03438ede ("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.

s2ram broke due to this KVM commit:

  b74f05d61b x86: kvmclock: abstract save/restore sched_clock_state

restore_sched_clock_state() methods use percpu data, therefore
they must run after %gs is initialized, but before mtrr_bp_restore()
(due to lockstat using sched_clock).

Move it to the correct place.

d06221c061 nouveau/bios: Fix tracking of BIOS image data
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.

ea71f98d68 nouveau: Fix crash when pci_ram_rom() returns a size of 0

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Subject:

Under some circumstances, pci_map_rom() can return a valid mapping
but a size of 0 (if it cannot find an image in the header).

This causes nouveau to try to kmalloc() a 0 sized pointer and
dereference it, which crashes.

72331bc0cd 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
route as if a packet was received on the specified interface", similar
to IPv4's 'inet_rtm_getroute()' interpretation.

450aed725c m68k/q40: Add missing platform check before registering platform devices
On multi-platform kernels, the Q40/Q60 platform devices should be
registered when running on Q40/Q60 only. Else it may crash later.

There is no indirect inclusions of the new asm/cmpxchg.h for m68k here.
Looking at most other architectures they include asm/cmpxchg.h in their
asm/atomic.h. M68k currently does not do this. Including this in atomic.h
fixes all m68k build problems.

81213b5e8a 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.

67378563df 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).

Thanks to Jorge Boncompte [DTI2] <jorge@dti2.net> for contributing to
this fix.

fbc729a446 hwmon: (k10temp) Add support for AMD Trinity CPUs
The on-chip northbridge's temperature sensor of the upcoming
AMD Trinity CPUs works the same as for the previous CPUs.
Since it has a different PCI-ID, we just add the new one to the list
supported by k10temp.
This allows to use the k10temp driver on those CPUs.

6f7805a8d9 hwmon: (w83627ehf) mark const init data with __initconst instead of __initdata
As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.

ce15a81da3 hwmon: (adm1031) Fix compiler warning
Some configurations produce the following compile warning:

drivers/hwmon/adm1031.c: In function 'set_fan_auto_channel':
drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function

While this is a false positive, it can easily be fixed by overloading the return
value from get_fan_auto_nearest with both register value and error return code
(the register value is never negative). Coincidentially, that also reduces
module size by a few bytes.

In some configurations, BUG() does not result in an endless loop but returns to
the caller. This results in the following compiler warning:

drivers/hwmon/f75375s.c: In function 'duty_mode_enabled':

Fix the warning by returning something sensible after BUG().
