There is no limit on number of MD5 keys an application can attach to a
tcp socket.
This patch adds a per tcp socket limit based
on /proc/sys/net/core/optmem_max
With current default optmem_max values, this allows about 150 keys on
64bit arches, and 88 keys on 32bit arches.

As the buffer is not necessarily accessible through the GTT at the time
of a GPU hang, and capturing some of its contents is far more valuable
than skipping it, provide a clflushed fallback read path. We still
prefer to read through the GTT as that is more consistent with the GPU
access of the same buffer. So example it will demonstrate any errorneous
tiling or swizzling of the command buffer as seen by the GPU.
This becomes necessary with use of CPU relocations and lazy GTT binding,
but could potentially happen anyway as a result of a pathological error.

Use the same pm_ops for all system suspend and resume paths. This isn't
ideal for suspend to disk with older CODECs as we'll suspend and then

If an idle_bias_off device is in any state other than off then it is still
active for some reason (typically a low power function such as accessory
detection). This wasn't an issue when the feature was implemented as we
always went to _ON for any active function, subsequent power improvements
have changed things.
With the modern way of doing things we should overhaul the infrastructure
to allow devices to explicitly take references for these functions but
that's a much more invasive change and will require driver updates to
deploy, this will bring the framework into line with the existing driver
set before we do that work.

The kmem_realloc() in xfs is given KM_* memory allocation flags. And it
allocates memory using kmalloc() after they are converted to gfp_mask
flags. In xlog_recover_add_to_cont_trans(), 0u is passed to kmem_realloc(),
instead of them. I guess it is preferred to use them, and here memory must
be allocated but don't have to be done with GFP_ATOMIC. So, this patch
changes it to KM_SLEEP.

There are few important bug fixes for LogFS
* tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream:
Logfs: Allow NULL block_isbad() methods
logfs: Grow inode in delete path
logfs: Free areas before calling generic_shutdown_super()
logfs: remove useless BUG_ON
MAINTAINERS: Add Prasad Joshi in LogFS maintiners
logfs: Propagate page parameter to __logfs_write_inode
logfs: set superblock shutdown flag after generic sb shutdown
logfs: take write mutex lock during fsync and sync
logfs: Prevent memory corruption
logfs: update page reference count for pined pages
Fix up conflict in fs/logfs/dev_mtd.c due to semantic change in what
"mtd->block_isbad" means in commit f2933e86ad: "Logfs: Allow NULL
block_isbad() methods" clashing with the abstraction changes in the
commits 7086c19d07: "mtd: introduce mtd_block_isbad interface" and
d58b27ed58: "logfs: do not use 'mtd->block_isbad' directly".
This resolution takes the semantics from commit f2933e86ad, and just
makes mtd_block_isbad() return zero (false) if the 'block_isbad'
function is NULL. But that also means that now "mtd_can_have_bb()"
always returns 0.
Now, "mtd_block_markbad()" will obviously return an error if the
low-level driver doesn't support bad blocks, so this is somewhat
non-symmetric, but it actually makes sense if a NULL "block_isbad"
function is considered to mean "I assume that all my blocks are always
good".
In order to be able to support proper RST messages for TCP MD5 flows, we
need to allow access to MD5 keys without locking listener socket.
This conversion is a nice cleanup, and shrinks size of timewait sockets
by 80 bytes.
IPv6 code reuses generic code found in IPv4 instead of duplicating it.
Control path uses GFP_KERNEL allocations instead of GFP_ATOMIC.

If a codec has both a front and a rear Line In, two controls both
named "Line Jack" will be created, which causes parsing to fail.
While a long term solution might be to name the jacks differently,
this extra check is consistent with what is already being done in many
auto-parsers, and will also protect against other cases when two
inputs have the same label.
