sound fixes for 4.1-rc1

Here are a few fixes that have been pending since the previous pull
request: a regression fix for HD-audio multiple SPDIF / HDMI devices,
several ALC256 codec fixes, a couple of i915 HDMI audio fixes, and
various small fixes.

Nothing exciting, just boring, but things good to have.

md updates for 4.1

Highlights:

- "experimental" code for managing md/raid1 across a cluster using
DLM. Code is not ready for general use and triggers a WARNING if used.
However it is looking good and mostly done and having in mainline
will help co-ordinate development.
- RAID5/6 can now batch multiple (4K wide) stripe_heads so as to
handle a full (chunk wide) stripe as a single unit.
- RAID6 can now perform read-modify-write cycles which should
help performance on larger arrays: 6 or more devices.
- RAID5/6 stripe cache now grows and shrinks dynamically. The value
set is used as a minimum.
- Resync is now allowed to go a little faster than the 'mininum' when
there is competing IO. How much faster depends on the speed of the
devices, so the effective minimum should scale with device speed to
some extent.

Initial ACPI support for arm64:

This series introduces preliminary ACPI 5.1 support to the arm64 kernel
using the "hardware reduced" profile. We don't support any peripherals
yet, so it's fairly limited in scope:

- Memory init (UEFI)
- ACPI discovery (RSDP via UEFI)
- CPU init (FADT)
- GIC init (MADT)
- SMP boot (MADT + PSCI)
- ACPI Kconfig options (dependent on EXPERT)

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull initial ACPI support for arm64 from Will Deacon:
"This series introduces preliminary ACPI 5.1 support to the arm64
kernel using the "hardware reduced" profile. We don't support any
peripherals yet, so it's fairly limited in scope:

- MEMORY init (UEFI)

- ACPI discovery (RSDP via UEFI)

- CPU init (FADT)

- GIC init (MADT)

- SMP boot (MADT + PSCI)

- ACPI Kconfig options (dependent on EXPERT)

ACPI for arm64 has been in development for a while now and hardware
has been available that can boot with either FDT or ACPI tables. This
has been made possible by both changes to the ACPI spec to cater for
ARM-based machines (known as "hardware-reduced" in ACPI parlance) but
also a Linaro-driven effort to get this supported on top of the Linux
kernel. This pull request is the result of that work.

These changes allow us to initialise the CPUs, interrupt controller,
and timers via ACPI tables, with memory information and cmdline coming
from EFI. We don't support a hybrid ACPI/FDT scheme. Of course,
there is still plenty of work to do (a serial console would be nice!)
but I expect that to happen on a per-driver basis after this core
series has been merged.

Anyway, the diff stat here is fairly horrible, but splitting this up
and merging it via all the different subsystems would have been
extremely painful. Instead, we've got all the relevant Acks in place
and I've not seen anything other than trivial (Kconfig) conflicts in
-next (for completeness, I've included my resolution below). Nearly
half of the insertions fall under Documentation/.

So, we'll see how this goes. Right now, it all depends on EXPERT and
I fully expect people to use FDT by default for the immediate future"

This update contains:
o RENAME_WHITEOUT support
o conversion of per-cpu superblock accounting to use generic counters
o new inode mmap lock so that we can lock page faults out of truncate, hole
punch and other direct extent manipulation functions to avoid racing mmap
writes from causing data corruption
o rework of direct IO submission and completion to solve data corruption issue
when running concurrent extending DIO writes. Also solves problem of running
IO completion transactions in interrupt context during size extending AIO
writes.
o FALLOC_FL_INSERT_RANGE support for inserting holes into a file via direct
extent manipulation to avoid needing to copy data within the file
o attribute block header field overflow fix for 64k block size filesystems
o Lots of changes to log messaging to be more informative and concise when
errors occur. Also prevent a lot of unnecessary log spamming due to cascading
failures in error conditions.
o lots of cleanups and bug fixes

x86: fix special __probe_kernel_write() tail zeroing case

Commit cae2a173fe94 ("x86: clean up/fix 'copy_in_user()' tail zeroing")
fixed the failure case tail zeroing of one special case of the x86-64
generic user-copy routine, namely when used for the user-to-user case
("copy_in_user()").

But in the process it broke an even more unusual case: using the user
copy routine for kernel-to-kernel copying.

Now, normally kernel-kernel copies are obviously done using memcpy(),
but we have a couple of special cases when we use the user-copy
functions. One is when we pass a kernel buffer to a regular user-buffer
routine, using set_fs(KERNEL_DS). That's a "normal" case, and continued
to work fine, because it never takes any faults (with the possible
exception of a silent and successful vmalloc fault).

But Jan Beulich pointed out another, very unusual, special case: when we
use the user-copy routines not because it's a path that expects a user
pointer, but for a couple of ftrace/kgdb cases that want to do a kernel
copy, but do so using "unsafe" buffers, and use the user-copy routine to
gracefully handle faults. IOW, for probe_kernel_write().

And that broke for the case of a faulting kernel destination, because we
saw the kernel destination and wanted to try to clear the tail of the
buffer. Which doesn't work, since that's what faults.

This only triggers for things like kgdb and ftrace users (eg trying
setting a breakpoint on read-only memory), but it's definitely a bug.
The fix is to not compare against the kernel address start (TASK_SIZE),
but instead use the same limits "access_ok()" uses.
