The MIPS syscall handler code used to return -ENOSYS on invalid
syscalls. Whilst this is expected, it caused problems for seccomp
filters because the said filters never had the change to run since
the code returned -ENOSYS before triggering them. This caused
problems on the chromium testsuite for filters looking for invalid
syscalls. This has now changed and the seccomp filters are always
run even if the syscall is invalid. We return -ENOSYS once we
return from the seccomp filters. Moreover, similar codepaths have
been merged in the process which simplifies somewhat the overall
syscall code.

Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.
Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

When the client goes to return a delegation, it should always update any
nfs4_state currently set up to use that delegation stateid to instead
use the open stateid. It already does do this in some cases,
particularly in the state recovery code, but not currently when the
delegation is voluntarily returned (e.g. in advance of a RENAME). This
causes the client to try to continue using the delegation stateid after
the DELEGRETURN, e.g. in LAYOUTGET.
Set the nfs4_state back to using the open stateid in
nfs4_open_delegation_recall, just before clearing the
NFS_DELEGATED_STATE bit.

Currently, we don't test if the state owner is in use before we try to
recover it. The problem is that if the refcount is zero, then the
state owner will be waiting on the lru list for garbage collection.
The expectation in that case is that if you bump the refcount, then
you must also remove the state owner from the lru list. Otherwise
the call to nfs4_put_state_owner will corrupt that list by trying
to add our state owner a second time.
Avoid the whole problem by just skipping state owners that hold no
state.

Currently, we are crediting all the calls to nfs_writepages_callback()
(i.e. the nfs_writepages() callback) to nfs_writepage(). Aside from
being inconsistent with the behaviour of the equivalent readpage/readpages
accounting, this also means that we cannot distinguish between bulk writes

More agressive inlining in recent versions of GCC have uncovered
a new set of warnings:
drivers/irqchip/irq-gic-v3-its.c: In function its_msi_prepare:
drivers/irqchip/irq-gic-v3-its.c:1148:26: warning: lpi_base may be used
uninitialized in this function [-Wmaybe-uninitialized]
dev->event_map.lpi_base = lpi_base;
^
drivers/irqchip/irq-gic-v3-its.c:1116:6: note: lpi_base was declared here
int lpi_base;
^
drivers/irqchip/irq-gic-v3-its.c:1149:25: warning: nr_lpis may be used
uninitialized in this function [-Wmaybe-uninitialized]
dev->event_map.nr_lpis = nr_lpis;
^
drivers/irqchip/irq-gic-v3-its.c:1117:6: note: nr_lpis was declared here
int nr_lpis;
^
The warning is fairly benign (there is no code path that could
actually use uninitialized variables), but let's silence it anyway
by zeroing the variables on the error path.

Pull block fixes from Jens Axboe:
"Another week, another round of fixes.
These have been brewing for a bit and in various iterations, but I
feel pretty comfortable about the quality of them. They fix real
issues. The pull request is mostly blk-mq related, and the only one
not fixing a real bug, is the tag iterator abstraction from Christoph.
But it's pretty trivial, and we'll need it for another fix soon.
Apart from the blk-mq fixes, there's an NVMe affinity fix from Keith,
and a single fix for xen-blkback from Roger fixing failure to free
requests on disconnect"
* 'for-linus' of git://git.kernel.dk/linux-block:
blk-mq: factor out a helper to iterate all tags for a request_queue
blk-mq: fix racy updates of rq->errors
blk-mq: fix deadlock when reading cpu_list
blk-mq: avoid inserting requests before establishing new mapping
blk-mq: fix q->mq_usage_counter access race
blk-mq: Fix use after of free q->mq_map
blk-mq: fix sysfs registration/unregistration race
blk-mq: avoid setting hctx->tags->cpumask before allocation
NVMe: Set affinity after allocating request queues
xen/blkback: free requests on disconnection
This reverts commit e51e38494a8ecc18650efb0c840600637891de2c: we
actually do want the device to work in extended W mode, as this is the
mode that allows us receiving multiple contact information.

During development it was found that a number of builds would panic
during the kernel init process, more specifically in 'delayed_fput()'.
The panic showed the kernel trying to access a memory address of
'0xb7fdc00' while traversing the 'delayed_fput_list' structure.
Comparing this memory address to the value of the pointer used on
builds that did not panic confirmed that the pointer on crashing
builds must have been corrupted at some stage earlier in the init
process.
By traversing the list earlier and earlier in the code it was found
that 'plat_mem_setup()' was responsible for corrupting the list.
Specifically the line:
memory = cvmx_bootmem_phy_alloc(mem_alloc_size,
__pa_symbol(&__init_end), -1,
0x100000,
CVMX_BOOTMEM_FLAG_NO_LOCKING);
Which would eventually call:
cvmx_bootmem_phy_set_size(new_ent_addr,
cvmx_bootmem_phy_get_size
(ent_addr) -
(desired_min_addr -
ent_addr));
Where 'new_ent_addr'=0x4800000 (the address of 'delayed_fput_list')
and the second argument (size)=0xb7fdc00 (the address causing the
kernel panic). The job of this part of 'plat_mem_setup()' is to
allocate chunks of memory for the kernel to use. At the start of
each chunk of memory the size of the chunk is written, hence the
value 0xb7fdc00 is written onto memory at 0x4800000, therefore the
kernel panics when it goes back to access 'delayed_fput_list' later
on in the initialisation process.
On builds that were not crashing it was found that the compiler had
placed 'delayed_fput_list' at 0x4800008, meaning it wasn't corrupted
(but something else in memory was overwritten).
As can be seen in the first function call above the code begins to
allocate chunks of memory beginning from the symbol '__init_end'.
The MIPS linker script (vmlinux.lds.S) however defines the .bss
section to begin after '__init_end'. Therefore memory within the
.bss section is allocated to the kernel to use (System.map shows
'delayed_fput_list' and other kernel structures to be in .bss).
To stop the kernel panic (and the .bss section being corrupted)
memory should begin being allocated from the symbol '_end'.

Commit 1a3d59579b ("MIPS: Tidy up FPU context switching") removed FP
context saving from the asm-written resume function in favour of reusing
existing code to perform the same task. However it only removed the FP
context saving code from the r4k_switch.S implementation of resume.
Remove it from the r2300_switch.S implementation too in order to prevent
attempting to save the FP context twice, which would likely lead to an
exception from the second save because the FPU had already been disabled
by the first save.
This patch has only been build tested, using rbtx49xx_defconfig.

Designware I2S uses tx empty and rx available signals as the DMA
handshaking signals. during music playing, if XRUN occurs,
i2s_stop() function will be executed and both tx and rx irq are
masked, when music continues to be played, i2s_start() is executed
but both tx and rx irq are not unmasked which cause I2S stop
sending DMA handshaking signal to DMA controller, and it finally
causes music playing will be stopped once XRUN occurs for the first
time.

systems -- broonie]

Commit 3a0f9aaee0 ("dm raid: round region_size to power of two")
intended to make sure that the default region size is a power of two.
However, the logic in that commit is incorrect and sets the variable
region_size to 0 or 1, depending on whether min_region_size is a power
of two.
Fix this logic, using roundup_pow_of_two(), so that region_size is
properly rounded up to the next power of two.
