ASoC: samsung: Fix non-DT use of I2S controller
The changes in commit
a5a56871f804e (ASoC: samsung: add support for exynos7
I2S controller) introduce a new variant_regs structure in the driver data
which is now mandatory for accessing registers. Unfortunately this is only
hooked up for DT platforms so non-DT platforms like my primary development
platform for audio are broken by this change and crash on boot.
Since the only non-DT user of these device is s3c64xx fix this by making
the standard samsung-i2s device be of type I2Sv3 and add a new I2Sv4 name
to the platform data section, currently using the I2Sv5 information which
should be about right.

The cause of problem and solution are well explained by Lars-Peter:
"The driver creates the mapping by calling irq_of_parse_and_map(), so it also
has to dispose the mapping. But the easy way out is to simply use
platform_get_irq() instead of irq_of_parse_map(). In this case the mapping is
not managed by the device but by the of core, so the device has not to dispose
the mapping."
Tested on a imx6q-sabresd board.

i2c: cadence: Set the hardware time-out register to maximum value
Cadence I2C controller has bug wherein it generates invalid read transactions
after timeout in master receiver mode. This driver does not use the HW
timeout and this interrupt is disabled but the feature itself cannot be
disabled. Hence, this patch writes the maximum value (0xFF) to this register.
This is one of the workarounds to this bug and it will not avoid the issue
completely but reduces the chances of error.

i2c: davinci: generate STP always when NACK is received
According to I2C specification the NACK should be handled as follows:
"When SDA remains HIGH during this ninth clock pulse, this is defined as the Not
Acknowledge signal. The master can then generate either a STOP condition to
abort the transfer, or a repeated START condition to start a new transfer."
[I2C spec Rev. 6, 3.1.6: http://www.nxp.com/documents/user_manual/UM10204.pdf]
Currently the Davinci i2c driver interrupts the transfer on receipt of a
NACK but fails to send a STOP in some situations and so makes the bus
stuck until next I2C IP reset (idle/enable).
For example, the issue will happen during SMBus read transfer which
consists from two i2c messages write command/address and read data:
S Slave Address Wr A Command Code A Sr Slave Address Rd A D1..Dn A P
<--- write -----------------------> <--- read --------------------->
The I2C client device will send NACK if it can't recognize "Command Code"
and it's expected from I2C master to generate STP in this case.
But now, Davinci i2C driver will just exit with -EREMOTEIO and STP will
not be generated.
Hence, fix it by generating Stop condition (STP) always when NACK is received.
This patch fixes Davinci I2C in the same way it was done for OMAP I2C

slab: fix nodeid bounds check for non-contiguous node IDs
The bounds check for nodeid in ____cache_alloc_node gives false
positives on machines where the node IDs are not contiguous, leading to
a panic at boot time. For example, on a POWER8 machine the node IDs are
typically 0, 1, 16 and 17. This means that num_online_nodes() returns
4, so when ____cache_alloc_node is called with nodeid = 16 the VM_BUG_ON
triggers, like this:
kernel BUG at /home/paulus/kernel/kvm/mm/slab.c:3079!
Call Trace:
.____cache_alloc_node+0x5c/0x270 (unreliable)
.kmem_cache_alloc_node_trace+0xdc/0x360

.kmem_cache_init+0x1dc/0x258
.start_kernel+0x2a0/0x568
start_here_common+0x20/0xa8
To fix this, we instead compare the nodeid with MAX_NUMNODES, and
additionally make sure it isn't negative (since nodeid is an int). The
check is there mainly to protect the array dereference in the get_node()
call in the next line, and the array being dereferenced is of size
MAX_NUMNODES. If the nodeid is in range but invalid (for example if the
node is off-line), the BUG_ON in the next line will catch that.

mm: fix anon_vma_clone() error treatment
Andrew Morton noticed that the error return from anon_vma_clone() was
being dropped and replaced with -ENOMEM (which is not itself a bug
because the only error return value from anon_vma_clone() is -ENOMEM).
I did an audit of callers of anon_vma_clone() and discovered an actual
bug where the error return was being lost. In __split_vma(), between
Linux 3.11 and 3.12 the code was changed so the err variable is used
before the call to anon_vma_clone() and the default initial value of
-ENOMEM is overwritten. So a failure of anon_vma_clone() will return
success since err at this point is now zero.
Below is a patch which fixes this bug and also propagates the error
return value from anon_vma_clone() in all cases.

Which wouldn't matter much, except it adds dst_mm next to src_mm,
assuming src_mm is already on the mmlist: which may not be so. Then if
pages are later swapped out from dst_mm, swapoff won't be able to find
where to replace them.
There's already a !non_swap_entry() test for stats: move that up before
the swap_duplicate() and the addition to mmlist.

ipc_addid() makes a new ipc identifier visible to everyone. New objects

doesn't work.

block: fix regression where bio_integrity_process uses wrong bio_vec iterator
bio integrity handling is broken on a system with LVM layered atop a
DIF/DIX SCSI drive because device mapper clones the bio, modifies the
clone, and sends the clone to the lower layers for processing.
However, the clone bio has bi_vcnt == 0, which means that when the sd
driver calls bio_integrity_process to attach DIX data, the
for_each_segment_all() call (which uses bi_vcnt) returns immediately
and random garbage is sent to the disk on a disk write. The disk of
course returns an error.
Therefore, teach bio_integrity_process() to use bio_for_each_segment()
to iterate the bio_vecs, since the per-bio iterator tracks which
bio_vecs are associated with that particular bio. The integrity
handling code is effectively part of the "driver" (it's not the bio
owner), so it must use the correct iterator function.
v2: Fix a compiler warning about abandoned local variables. This
patch supersedes "block: bio_integrity_process uses wrong bio_vec
iterator". Patch applies against 3.18-rc6.

drm/i915: More cautious with pch fifo underruns
Apparently PCH fifo underruns are tricky, we have plenty reports that
we see the occasional underrun (especially at boot-up).
So for a change let's see what happens when we don't re-enable pch
fifo underrun reporting when the pipe is disabled. This means that the
kernel can't catch pch fifo underruns when they happen (except when
all pipes are on on the pch). But we'll still catch underruns when
disabling the pipe again. So not a terrible reduction in test
coverage.
Since the DRM_ERROR is new and hence a regression plan B would be to
revert it back to a debug output. Which would be a lot worse than this
hack for underrun test coverage in the wild. See the referenced
discussions for more.

Merge branch 'linux-3.18' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
Just a couple of fixes for the fallout from the fence rework.
* 'linux-3.18' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/gf116: remove copy1 engine
drm/nouveau: prevent stale fence->channel pointers, and protect with rcu
drm/nouveau/fifo/g84-: ack non-stall interrupt before handling it

drm/nouveau/gf116: remove copy1 engine
Indications are that no GF116's actually have a copy engine there, but
actually have the decompression engine. This engine can be made to do
copies, but that should be done separately.
Unclear why this didn't turn up on all GF116's, but perhaps the
non-mobile ones came with enough VRAM to not trigger ttm migrations in
test scenarios.
