Pull perf updates from Ingo Molnar:
"Most of the changes are for tooling, the main changes in this cycle were:
- Improve Intel-PT hardware tracing support, both on the kernel and
on the tooling side: PTWRITE instruction support, power events for
C-state tracing, etc. (Adrian Hunter)
- Add support to measure SMI cost to the x86 architecture, with
tooling support in 'perf stat' (Kan Liang)
- Support function filtering in 'perf ftrace', plus related
improvements (Namhyung Kim)
- Allow adding and removing fields to the default 'perf script'
columns, using + or - as field prefixes to do so (Andi Kleen)
- Allow resolving the DSO name with 'perf script -F brstack{sym,off},dso'
(Mark Santaniello)
- Add perf tooling unwind support for PowerPC (Paolo Bonzini)
- ... and various other improvements as well"

Pull locking updates from Ingo Molnar:
"The main changes in this cycle were:
- Add CONFIG_REFCOUNT_FULL=y to allow the disabling of the 'full'
(robustness checked) refcount_t implementation with slightly lower
runtime overhead. (Kees Cook)
The lighter weight variant is the default. The two variants use the
same API. Having this variant was a precondition by some
maintainers to merge refcount_t cleanups.
- Add lockdep support for rtmutexes (Peter Zijlstra)
- liblockdep fixes and improvements (Sasha Levin, Ben Hutchings)
- ... misc fixes and improvements"

Pull RCU updates from Ingo Molnar:
"The sole purpose of these changes is to shrink and simplify the RCU
code base, which has suffered from creeping bloat over the past couple
of years. The end result is a net removal of ~2700 lines of code:
79 files changed, 1496 insertions(+), 4211 deletions(-)
Plus there's a marked reduction in the Kconfig space complexity as
well, here's the number of matches on 'grep RCU' in the .config:
before after
x86-defconfig 17 15
x86-allmodconfig 33 20"

Pull objtool updates from Ingo Molnar:
"This is an extensive rewrite of the objdump tool to track all stack
pointer modifications through the machine instructions of disassembled
functions found in kernel .o files.
This re-design removes the prior dependency on CONFIG_FRAME_POINTERS,
with the goal to prepare the tool to generate kernel debuginfo data in
the future. There's also an increase in checking/tracking robustness
as a side effect as well.
No (intended) changes to existing functionality"

Pull core block/IO updates from Jens Axboe:
"This is the main pull request for the block layer for 4.13. Not a huge
round in terms of features, but there's a lot of churn related to some
core cleanups.
Note this depends on the UUID tree pull request, that Christoph
already sent out.
This pull request contains:
- A series from Christoph, unifying the error/stats codes in the
block layer. We now use blk_status_t everywhere, instead of using
different schemes for different places.
- Also from Christoph, some cleanups around request allocation and IO
scheduler interactions in blk-mq.
- And yet another series from Christoph, cleaning up how we handle
and do bounce buffering in the block layer.
- A blk-mq debugfs series from Bart, further improving on the support
we have for exporting internal information to aid debugging IO
hangs or stalls.
- Also from Bart, a series that cleans up the request initialization
differences across types of devices.
- A series from Goldwyn Rodrigues, allowing the block layer to return
failure if we will block and the user asked for non-blocking.
- Patch from Hannes for supporting setting loop devices block size to
that of the underlying device.
- Two series of patches from Javier, fixing various issues with
lightnvm, particular around pblk.
- A series from me, adding support for write hints. This comes with
NVMe support as well, so applications can help guide data placement
on flash to improve performance, latencies, and write
amplification.
- A series from Ming, improving and hardening blk-mq support for
stopping/starting and quiescing hardware queues.
- Two pull requests for NVMe updates. Nothing major on the feature
side, but lots of cleanups and bug fixes. From the usual crew.
- A series from Neil Brown, greatly improving the bio rescue set
support. Most notably, this kills the bio rescue work queues, if we
don't really need them.
- Lots of other little bug fixes that are all over the place"

Pull uuid subsystem from Christoph Hellwig:
"This is the new uuid subsystem, in which Amir, Andy and I have started
consolidating our uuid/guid helpers and improving the types used for
them. Note that various other subsystems have pulled in this tree, so
I'd like it to go in early.
UUID/GUID summary:
- introduce the new uuid_t/guid_t types that are going to replace the
somewhat confusing uuid_be/uuid_le types and make the terminology
fit the various specs, as well as the userspace libuuid library.
(me, based on a previous version from Amir)
- consolidated generic uuid/guid helper functions lifted from XFS and
libnvdimm (Amir and me)
- conversions to the new types and helpers (Amir, Andy and me)"

Contrary to popular belief, PPIs connected to a GICv3 to not have
an affinity field similar to that of GICv2. That is consistent
with the fact that GICv3 is designed to accomodate thousands of
CPUs, and fitting them as a bitmap in a byte is... difficult.

When a process runs out of stack the parisc kernel wrongly faults with SIGBUS
instead of the expected SIGSEGV signal.
This example shows how the kernel faults:
do_page_fault() command='a.out' type=15 address=0xfaac2000 in libc-2.24.so[f8308000+16c000]
trap #15: Data TLB miss fault, vm_start = 0xfa2c2000, vm_end = 0xfaac2000
The vma->vm_end value is the first address which does not belong to the vma, so
adjust the check to include vma->vm_end to the range for which to send the
SIGSEGV signal.
This patch unbreaks building the debian libsigsegv package.

Architectures with a compat syscall table must put compat_sys_keyctl()
in it, not sys_keyctl(). The parisc architecture was not doing this;
fix it.

Pull MIPS fixes from Ralf Baechle:
"Here's a final round of fixes for 4.12:
- Fix misordered instructions in assembly code making kenel startup
via UHB unreliable.
- Fix special case of MADDF and MADDF emulation.
- Fix alignment issue in address calculation in pm-cps on 64 bit.
- Fix IRQ tracing & lockdep when rescheduling
- Systems with MAARs require post-DMA cache flushes.
The reordering fix and the MADDF/MSUBF fix have sat in linux-next for
a number of days. The others haven't propagated from my pull tree to
linux-next yet but all have survived manual testing and Imagination's
automated test system and there are no pending bug reports"

CONFIG_REFCOUNT_FULL=y (correctly) does not provide a refcount_sub(),
which should not be part of proper refcount design patterns.
Remove the erroneous extern and the later !CONFIG_REFCOUNT_FULL
accidental implementation.

Pull pinctrl fix from Linus Walleij:
"Brian noticed that this regression has not got a proper fix for the
entire merge window and consequently we need to revert the offending
commit.
It's part of the RT-mainstream work, the dance goes like this, two
steps forward, one step back.
Summary:
- A last fix for v4.12, an IRQ problem reported early in the merge
window appears not to have been properly fixed, so the offending
commit will be reverted and we will find the proper fix for v4.13.
Hopefully"
