Pull powerpc fixes from Ben Herrenschmidt:
"The main thing that caused problem was that CONFIG_CPU_LITTLE_ENDIAN
got turned on with allyesconfig and such, which is not a very good
idea especially since it requires a newer toolchain than what most
people have.
So we turned it into a choice instead that defaults to big endian"

commit 566c09c53455d7c4f1 raid5: relieve lock contention in get_active_stripe()
modified the locking in get_active_stripe() reducing the range
protected by the (highly contended) device_lock.
Unfortunately it reduced the range too much opening up some races.
One race can occur if get_priority_stripe runs between the
test on sh->count and device_lock being taken.
This will mean that sh->lru is not empty while get_active_stripe
thinks ->count is zero resulting in a 'BUG' firing.
Another race happens if __release_stripe is called immediately
after sh->count is tested and found to be non-zero. If STRIPE_HANDLE
is not set, get_active_stripe should increment ->active_stripes
when it increments ->count from 0, but as it didn't think it was 0,
it doesn't.
Extending device_lock to cover the test on sh->count close these
races.
While we are here, fix the two BUG tests:
-If count is zero, then lru really must not be empty, or we've
lock the stripe_head somehow - no other tests are relevant.
-STRIPE_ON_RELEASE_LIST is completely independent of ->lru so
testing it is pointless.

commit 7a0a5355cbc71efa md: Don't test all of mddev->flags at once.
made most tests on mddev->flags safer, but missed one.
When
commit 260fa034ef7a4ff8b7306 md: avoid deadlock when dirty buffers during md_stop.
added MD_STILL_CLOSED, this caused md_check_recovery to misbehave.
It can think there is something to do but find nothing. This can
lead to the md thread spinning during array shutdown.

The source of this problem is that SCSI hosts are removed from
ATA ports after calling ata_tport_delete() which removes the
port's sysfs directory, among other things. Now, after commit
bcdde7e221a8, the sysfs directory is removed along with all of
its subdirectories that include the SCSI host's sysfs directory
and its subdirectories at this point. Consequently, when
device_del() is finally called for any child device of the SCSI
host and tries to remove its "power" group (which is already
gone then), it triggers the above warning.
To make the warnings go away, change the removal ordering in
ata_port_detach() so that the SCSI host is removed from the
port before ata_tport_delete() is called.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

The PL061 driver had the irqdomain initialization in an unfortunate
place: when used with device tree (and thus passing the base IRQ
0) the driver would work, as this registers an irqdomain and waits
for mappings to be done dynamically as the devices request their
IRQs, whereas when booting using platform data the irqdomain core
would attempt to allocate IRQ descriptors dynamically (which works
fine) but also to associate the irq_domain_associate_many() on all
IRQs, which in turn will call the mapping function which at this
point will try to set the type of the IRQ and then tries to acquire
a non-initialized spinlock yielding a backtrace like this:

This moves the irqdomain initialization to a point where the spinlock
and GPIO chip are both fully propulated, so the callbacks can be used
without crashes.
I had some problem reproducing the crash, as the devm_kzalloc():ed
zeroed memory would seemingly mask the spinlock as something OK,
but by poisoning the lock like this:
u32 *dum;
dum = (u32 *) &chip->lock;
*dum = 0xaaaaaaaaU;
I could reproduce, fix and test the patch.

UHID allows short writes so user-space can omit unused fields. We
automatically set them to 0 in the kernel. However, the 64/32 bit
compat-handler didn't do that in the UHID_CREATE fallback. This will
reveal random kernel heap data (of random size, even) to user-space.

Since commit 110dd8f19df5 "[SCSI] libsas: fix scr_read/write users and
update the libata documentation" we have been passing pmp=1 and is_cmd=0
to ata_tf_to_fis(). Praveen reports that eSATA attached drives do not
discover correctly. His investigation found that the BIOS was passing
pmp=0 while Linux was passing pmp=1 and failing to discover the drives.
Update libsas to follow the libata example of pulling the pmp setting
from the ata_link and correct is_cmd to be 1 since all tf's submitted
through ->qc_issue are commands. Presumably libsas lldds do not care
about is_cmd as they have sideband mechanisms to perform link
management.

Some features can be configured by the companion I2C chips,
which may not be available at the probe time. Fix the issue
by returning -EPROBE_DEFER when the MMC controller slots
are not configured.
While at it, let's also add minimal device tree support so
omap24xx platforms can use this driver without legacy mode
since we claim to support device tree for mach-omap2 based
systems.
Although adding the minimal device tree support is not strictly
a fix, it does remove one of the last blockers for dropping a
bunch of legacy platform data for mach-omap2.

I2C IP block expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:
[ 7.302154] =====================================
[ 7.307128] [ BUG: bad unlock balance detected! ]
[ 7.312103] 3.12.0-los.git-2093492-00120-g5e01dc7 #3 Not tainted
[ 7.318450] -------------------------------------
[ 7.323425] kworker/u2:1/12 is trying to release lock (&ddata->mutex) at:
[ 7.330657] [<c031b760>] acx565akm_enable+0x12c/0x18c
[ 7.335998] but there are no more locks to release!
Fix by removing double unlock and handling the locking completely inside
acx565akm_panel_power_on() when doing the power on.

Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard
backlight settings"): avoid messing up the state on resume. Leave it to
what was before suspending as it's anyway likely that we still don't
know what value we should write to the EC registers. This fix is also
required in 3.12

Header file <acpi/acpi.h> contains environemnt settings and architecture
specific implementation that should be included before any other ACPICA
headers in order to keep a consistent build environment for ACPICA users.
The following internal ACPICA header files should be included from
<acpi/acpi.h> and should not be included by other kernel files:
<acpi/acpiosxf.h>
<acpi/acpixf.h>
Clean up incorrect inclusions of these files from non-ACPICA source
files.

zsmalloc encodes a handle using the pfn and an object
index. On hardware platforms with physical memory starting
at 0x0 the pfn can be 0. This causes the encoded handle to be
0 and is incorrectly interpreted as an allocation failure.
This issue affects all current and future SoCs with physical
memory starting at 0x0. All MSM8974 SoCs which includes
Google Nexus 5 devices are affected.
To prevent this false error we ensure that the encoded handle
will not be 0 when allocation succeeds.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First round of fixes for IIO in the 3.13 cycle.
The usual mixed bag of fixes.
* 3 cases where kconfig dependencies were missing. We need to keep a closer
eye on this in new drivers.
* hid_sensors was abusing the iio_dev->trigger pointer. We had a round
of clearing this out some time ago but this driver clearly slipped through.
* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
concertive effort to finish removing.
* Avoid a double free introduced by recent buffer reference counting in the
one driver that (quite reasonably!) does things differently (am335x)
* A missing mutex_unlock in kxsd9 that means that driver has been non
functional for some time and no one noticed (including me who for once
actually has one of the supported devices).
* An incorrect assumption about the parameters of sign_extend32 in mcp3422.
So nothing controversial. The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.

The number of bytes transmitted was not updated correctly, if several CAN
messages (with different length) were transmitted in one 'bunch'. Thus
programs like 'ifconfig' showed wrong transmit byte counts. Reason was, that
the message object whose DLC is to be read was not necessarily the active one
at the time when
priv->read_reg(priv, C_CAN_IFACE(MSGCTRL_REG, 0)) & IF_MCONT_DLC_MASK;
was executed.

The c_can driver contians a callpath (c_can_poll -> c_can_state_change ->
c_can_get_berr_counter) which may call pm_runtime_get_sync() from the IRQ
handler, which is not allowed and results in "BUG: scheduling while atomic".
This problem is fixed by introducing __c_can_get_berr_counter, which will not
call pm_runtime_get_sync().

This patch fixes the issue that the sja1000_interrupt() function may have
returned IRQ_NONE without processing the optional pre_irq() and post_irq()
function before. Further the irq processing counter 'n' is moved to the end of
the while statement to return correct IRQ_[NONE|HANDLED] values at error
conditions.

commit b8d181e408af (staging: drm/imx: add drm plane support) added a file
to the make target for DRM_IMX_IPUV3 but didn't adjust the objs required
to actually build that as a module. Kbuild got confused and this lead to
link errors like:
ERROR: "ipu_plane_disable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
ERROR: "ipu_plane_enable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
Additionally, it added a call to imx_drm_crtc_id which also fails with a
link error as above. To fix this, we adjust the make target with the proper
objs, which will change the name of the resulting .ko. We also add an
EXPORT_SYMBOL_GPL for imx_drm_crtc_id.
