06980b24cf watchdog: meson: remove magic value for reboot
This patch removes the magic value used for rebooting the board. This
value is useless and leads to a static checker warning as reported by
Dan Carpenter.

c5ec618fbf watchdog: sunxi: Add A31 watchdog support
This patch adds support for the watchdog hardware found in A31 and
newer SoCs. This new hardware has registers at different offsets, and
the system reset control has been split out of the "mode" register
into a new "configuration" register.

Differences not supported by this driver include separate interrupt
lines for each watchdog, instead of sharing an interrupt line and
registers with the timer block.

f2147de334 watchdog: sunxi: support parameterized compatible strings
This patch adds support for hardware parameters tied to compatible
strings, so similar hardware can reuse the driver.

This will be used to support the newer watchdog found in A31 and
later SoCs. Differences in the new hardware include separate
interrupt lines for each watchdog, and corresponding interrupt
control/status registers. Watchdog control registers were also
slightly rearranged.

Also replace ioread32()/iowrite32() with readl()/writel() in various
places changed.

05e487d905 watchdog: qcom: register a restart notifier
The WDT's BITE_TIME warm-reset behavior can be leveraged as a last
resort mechanism for triggering chip reset.  Usually, other restart
methods (such as PS_HOLD) are preferrable for issuing a more complete
reset of the chip.  As such, keep the priority of the watchdog notifier
low.

f286e1335f watchdog: s3c2410: add restart handler

With the introduction of the restart handlers, this code can now move into
driver itself, removing the need for arch-specific code.

b569c1c622 net: bpf: arm64: address randomize and write protect JIT code
This is the ARM64 variant for 314beb9bca ("x86: bpf_jit_comp: secure bpf
jit against spraying attacks").

Thanks to commit 11d91a770f ("arm64: Add CONFIG_DEBUG_SET_MODULE_RONX
support") which added necessary infrastructure, we can now implement
RO marking of eBPF generated JIT image pages and randomize start offset
for the JIT code, so that it does not reside directly on a page boundary
anymore. Likewise, the holes are filled with illegal instructions: here
we use BRK #0x100 (opcode 0xd4202000) to trigger a fault in the kernel
(unallocated BRKs would trigger a fault through do_debug_exception). This
seems more reliable as we don't have a guaranteed undefined instruction
space on ARM64.

This is basically the ARM64 variant of what we already have in ARM via
commit 55309dd3d4 ("net: bpf: arm: address randomize and write protect
JIT code"). Moreover, this commit also presents a merge resolution due to
conflicts with commit 60a3b2253c ("net: bpf: make eBPF interpreter images
read-only") as we don't use kfree() in bpf_jit_free() anymore to release
the locked bpf_prog structure, but instead bpf_prog_unlock_free() through
a different allocator.

JIT tested on aarch64 with BPF test suite.

2a0b5c0d19 arm64: Align less than PAGE_SIZE pgds naturally
When the pgd size is smaller than PAGE_SIZE, pgd_alloc() uses kzalloc()
to save space. However, this is not always naturally aligned as required
by the architecture. This patch creates a kmem_cache for pgd allocations
with the correct alignment.

The current kernel configurations with 4K pages + 39-bit VA and 64K
pages + 42-bit VA use a full page for the pgd and are not affected. The
patch is required for 48-bit VA with 64K pages where the pgd is 512
bytes.

40ac948e02 drm/gt215/gr: fix initialisation on gddr5 boards
The binary driver modifies the default context to have this value, rather
than 0x3d0040, *after* it's filled the buffer with the usual golden data.

We don't really have anything in place to locate the correct offset to do
these type of modifications outside of the generation function, so this
will have to do.

6acce400d9 ALSA: hda - hdmi: Fix missing ELD change event on plug/unplug
The ELD ALSA control change event is sent by hdmi_present_sense() when
eld_changed is true.

Currently, it is only true when the ELD buffer contents have been
modified. However, the user-visible ELD controls also change to a
zero-length value and back when eld_valid is unset/set, and no event is
currently sent in such cases (such as when unplugging or replugging a
sink).

Fix the code to always set eld_changed if eld_valid value is changed,
and therefore to always send the change event when the user-visible
value changes.

f0b127fbfd ALSA: usb-audio: Add support for Steinberg UR22 USB interface
Adding support for Steinberg UR22 USB interface via quirks table patch

See Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1317244
Also see threads:
http://linux-audio.4202.n7.nabble.com/Support-for-Steinberg-UR22-Yamaha-USB-chipset-0499-1509-tc82888.html#a82917
http://www.steinberg.net/forums/viewtopic.php?t=62290

Tested by at least 4 people judging by the threads.
Did not test MIDI interface, but audio output and capture both are
functional. Built 3.17 kernel with this driver on Ubuntu 14.04 & tested with mpg123
Patch applied to 3.13 Ubuntu kernel works well enough for daily use.

4d3639ac3c ARM: SoC fixes for -rc1
A batch of fixes that have come in during the merge window.
 
 Some of them are defconfig updates for things that have now landed,
 some errata additions and a few general scattered fixes.
 
 There's also a qcom DT update that adds support for SATA on AP148,
 and basic support for Sony Xperia Z1 and CM-QS600 platforms that seemed
 isolated enough that we could merge it even if it's late.

ab074ade9c Merge git://git.infradead.org/users/eparis/audit
Pull audit updates from Eric Paris:
 "So this change across a whole bunch of arches really solves one basic
  problem.  We want to audit when seccomp is killing a process.  seccomp
  hooks in before the audit syscall entry code.  audit_syscall_entry
  took as an argument the arch of the given syscall.  Since the arch is
  part of what makes a syscall number meaningful it's an important part
  of the record, but it isn't available when seccomp shoots the
  syscall...

  For most arch's we have a better way to get the arch (syscall_get_arch)
  So the solution was two fold: Implement syscall_get_arch() everywhere
  there is audit which didn't have it.  Use syscall_get_arch() in the
  seccomp audit code.  Having syscall_get_arch() everywhere meant it was
  a useless flag on the stack and we could get rid of it for the typical
  syscall entry.

  The other changes inside the audit system aren't grand, fixed some
  records that had invalid spaces.  Better locking around the task comm
  field.  Removing some dead functions and structs.  Make some things
  static.  Really minor stuff"
