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"

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.

gpio: acpi: Skip _AEI entries without a handler rather then aborting the scan
gpiolib: fix filtering out unwanted events
Intel PT:
- Support "ptwrite" instructio, a way to stuff 32 or 64 bit values into
the Intel PT trace (Adrian Hunter)
- Support power events in Intel PT to report changes to C-state (Adrian
Hunter)
- Synthesize Intel PT events as PERF_RECORD_SAMPLE records with a
perf_event_attr.type (PERF_TYPE_SYNTH) just after the range used by the
kernel, i.e. right after what is allocated for PMUs, at INT_MAX + 1U,
attr.config will have the identification for the synthesized event and
the PERF_SAMPLE_RAW payload will have its fields (Adrian Hunter)
Infrastructure:
- Remove warning() and error(), using instead pr_warning() and
pr_error(), consolidating error reporting (Arnaldo Carvalho de Melo)
- Add platform dependency to 'perf test 15' (Thomas Richter)

One is for a crash when using the :mod: trace probe command into
stack_trace_filter. This bug was introduced during the last merge
window.
The other was there forever. It's a small bug that makes it impossible
to name a module function for kprobes when the module starts with a digit.

ftrace: Fix regression with module command in stack_trace_filter
uapi/linux/a.out.h uses a number of predefined macros that are
deprecated because they're in the application namespace
(e.g. '#ifdef linux' instead of '#ifdef __linux__').
This patch either corrects or just removes them if they are not
applicable to Linux.
The primary reason this is worth bothering to fix, considering how
obsolete a.out binary support is, is that the GCC build process
considers this such a severe error that it will copy the header into a
private directory and change the macro names, which causes future
updates to the header to be masked. This header probably doesn't get
updated very often anymore, but it is the _only_ uapi header that gets
this treatment, so IMHO it is worth patching just to drive that number
all the way to zero.
