This patch has the driver automatically reread partitions if a namespace
has a separate metadata format. Previously revalidating a disk was
sufficient to get the correct capacity set on such formatted drives,
but partitions that may exist would not have been surfaced.

Pull file locking updates from Jeff Layton:
"I had thought that I was going to get away without a pull request this
cycle. There was a NFSv4 file locking problem that cropped up that I
tried to fix in the NFSv4 code alone, but that fix has turned out to
be problematic. These patches fix this in the correct way.
Note that this touches some NFSv4 code as well. Ordinarily I'd wait
for Trond to ACK this, but he's on holiday right now and the bug is
rather nasty. So I suggest we merge this and if he raises issues with
it we can sort it out when he gets back"

The end of jfs_rename(), which is also used by the error paths,
included a call to IWRITE_UNLOCK(new_ip) after labels out1, out2
and out3. If we come in through these labels, IWRITE_LOCK() has not
been called yet.
In moving that call to the correct spot, I also moved some
exceptional truncate code earlier as well, since the early error
paths don't need to deal with it, and I renamed out4: to out_tx: so
a future patch by Jan Kara doesn't need to deal with renumbering or
confusing out-of-order labels.

"With the release of 4.2-rc2 done, we should not be seeing any new code
added that gets upset by this small code move, and we've banked yet
another complete week of testing with this move in place on top of
4.2-rc1 via linux-next to ensure that remained true.
Given that, I'd like to put it in now so that people formulating new
work for 4.3-rc1 will be exposed to the ever so slightly stricter (but
sensible) requirements wrt. whether they are needing init.h vs.
module.h macros, even if they are not using linux-next.
The diffstat of the move is slightly asymmetrical due to needing to
leave behind a couple #ifdef in the old location and add the same ones
to the new location, but other than that, it is a 1:1 move, complete
with the module_init/exit trailing semicolon that we can't fix. That
is, until/unless someone does a tree-wide sed fix of all the
approximately 800 currently in tree users relying on it"

Fix the start address calculation when overlay is partially off screen.
fb->bits_per_pixel is not set for YUV formats, and is always zero, which
led to the first component always starting at zero.
Use drm_format_plane_cpp() instead.
This also revealed a problem in that YUYV formats toggle the U/V data
for odd pixel start address offsets. We try to rectify that by
toggling the U/V swap, which for the most part works, but seemingly
introduces a flicker for one scan frame of swapped U/V.
However, these changes result in an overall improvement.

Nothing was waking up the overlay plane wait queue, so we were fully
reliant on the HZ/25 wait timing out to make progress. Fix the lack
of wake-up.
We were also mis-handling the wait_event_timeout() return value - this
returns an unsigned integer of the remaining time, or zero on timeout
and the condition evaluated false. Checking this for less than zero
is not sane.

Commit 5ef7bbb09f ("perf tools: Allow to specify custom linker
command") was meant to enable usage non $(CROSS_COMPILE)ld linker during
perf building.
But implementation didn't take into account the fact that LD is a
pre-defined variable in GNU Make. I.e. it is always defined.
Which means there's no point to check "LD ?= ..." because it will never
succeed.
And so LD will be either that explicitly passed to make like this:
------->8-------
make LD=path_to_my_ld ...
------->8-------
or default value, which is host's "ld".
Latter leads to failure of cross-linkage because instead of cross linker
"$(CROSS_COMPILE)ld" host's "ld" is used.
Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld
with user defined LD on command-line.
As a reference was used implementation in "tools/lib/traceevent/Makefile".
Build tested for x86_64 and ARC.
Thanks Jiri for this hint.

- Fix 'perf report' and 'perf top' handling of the '--dsos DSO-LIST',
'--comms COMM-LIST' and '--symbols SYM-LIST' command line options,
that were segfaulting due to not considering those lists as filters
in the hists browser TUI code. (Arnaldo Carvalho de Melo)

Audio-in was incorrectly routed to Line In. It should be Mic3L as per
schematic.
Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.
With these changes, I can record audio with a pair of proliferate TRRS earbuds.

CONFIG_HAVE_ARM_SCU only gets selected if CONFIG_SMP is selected in an OMAP
system, however AM43XX needs this option regardless of CONFIG_SMP and also
for an AM43XX only build as it is important for controlling power in the SoC.
Without this we cannot suspend the CPU for SoC suspend or cpuidle. The
ARM Cortex A9 needs SCU CPU Power Status bits to be set to off mode in order
for the PRCM to transition the MPU to low power modes.

drm: add support for tiled/compressed/etc modifier in addfb2
Missed the structure packing/alignment problem where 64-bit
members were added after the odd number of 32-bit ones. This
makes the compiler produce structures of different sizes under
32- and 64-bit x86 targets and makes the ioctl need explicit
compat handling.

- Correct compatible string for i.MX27 GPT which actually shares the
same programming model as i.MX21 GPT rather than i.MX1 one.
- Add missing #io-channel-cells property for i.MX23 LRADC device, which
is required for the device to be an IIO provider.
- Correct HSYNC/VSYNC pins and add ddc-i2c-bus property for TVE device
on imx53-qsb to work properly.
- Always enable PU domain if CONFIG_PM is not set. This fixes a couple
of failure scenarios which will hang the system if one of the devices
in the PU domain is accessed.

Boris reported that the sparse_irq protection around __cpu_up() in the
generic code causes a regression on Xen. Xen allocates interrupts and
some more in the xen_cpu_up() function, so it deadlocks on the
sparse_irq_lock.
There is no simple fix for this and we really should have the
protection for all architectures, but for now the only solution is to
move it to x86 where actual wreckage due to the lack of protection has
been observed.

This changes large master transfers to do shorter read/write rather than
return -EINVAL. User space will now be able to optimistically request a
large transfer and get at least some data.
This also removes comments suggesting on how to implement large
transfers. Current vme_master_* read and write implementations use CPU
copies that don't produce burst PCI accesses and subsequently no block
transfer on VME bus. In the end overall performance is quiet low and it
can't be fixed by doing direct copy to user space. Much easier solution
would be to just reuse kernel buffer.
