Pull powerpc updates from Michael Ellerman:
"Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9
when using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts
as well as "normal" interrupts, and then use that to implement
local_t for a ~4x speedup vs the current atomics-based
implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor
Interface (OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe
hotpluggable memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit
VDSO.
- Freescale updates from Scott: fixes for CPM GPIO and an FSL PCI
erratum workaround, plus a minor cleanup patch.
As well as quite a lot of other changes all over the place, and small
fixes and cleanups as always.

skd includes slab_def.h to get access to the slab cache object size.
However, including this header breaks when we use SLUB or SLOB instead of
the SLAB allocator, since the structure layout is completely different,
as shown by this warning when we build this driver in one of the invalid
configurations with link-time optimizations enabled:
include/linux/slab.h:715:0: error: type of 'kmem_cache_size' does not match original declaration [-Werror=lto-type-mismatch]
unsigned int kmem_cache_size(struct kmem_cache *s);
mm/slab_common.c:77:14: note: 'kmem_cache_size' was previously declared here
unsigned int kmem_cache_size(struct kmem_cache *s)

mm/slab_common.c:77:14: note: code may be misoptimized unless -fno-strict-aliasing is used
include/linux/slab.h:147:0: error: type of 'kmem_cache_destroy' does not match original declaration [-Werror=lto-type-mismatch]

mm/slab_common.c:858:6: note: 'kmem_cache_destroy' was previously declared here

mm/slab_common.c:534:1: note: 'kmem_cache_create' was previously declared here
kmem_cache_create(const char *name, size_t size, size_t align,
^
This removes the header inclusion and instead uses the kmem_cache_size()
interface to get the size in a reliable way.

It's expensive to set buffer flags that are already set, because that
causes a costly cache line transition.
A common case is setting the "verified" flag during ext4 writes.
This patch checks for the flag being set first.
With the AIM7/creat-clo benchmark testing on a 48G ramdisk based-on ext4
file system, we see 3.3%(15431->15936) improvement of aim7.jobs-per-min on
a 2-sockets broadwell platform.
What the benchmark does is: it forks 3000 processes, and each process do
the following:
a) open a new file
b) close the file
c) delete the file
until loop=100*1000 times.
The original patch is contributed by Andi Kleen.

Pull drm updates from Dave Airlie:
"This seems to have been a comparatively quieter merge window, I assume
due to holidays etc. The "biggest" change is AMD header cleanups, which
merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
with the etnaviv driver wanting to reuse the code, hopefully other drivers
can go in the same direction.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The core framework has a handful of patches this time around, mostly
due to the clk rate protection support added by Jerome Brunet.
This feature will allow consumers to lock in a certain rate on the
output of a clk so that things like audio playback don't hear pops
when the clk frequency changes due to shared parent clks changing
rates. Currently the clk API doesn't guarantee the rate of a clk stays
at the rate you request after clk_set_rate() is called, so this new
API will allow drivers to express that requirement.
Beyond this, the core got some debugfs pretty printing patches and a
couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h
file causes small one-liners in all the architecture Kbuild files.
Overall, the driver diff seems to be the normal stuff that comes all
the time to fix little problems here and there and to support new
hardware.
Summary:
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs"

This is a new approach to the old problem. It was first proposed by
Steven Rostedt on Kernel Summit 2017. It marks a context in which
the console_lock owner calls console drivers and could not sleep.
On the other side, printk() callers could detect this state and use
a busy wait instead of a simple console_trylock(). Finally, the
console_lock owner checks if there is a busy waiter at the end of
the special context and eventually passes the console_lock to the
waiter.
The hand-off works surprisingly well and helps in many situations.
Well, there is still a possibility of the softlockup, for example,
when the flood of messages stops and the last owner still has too
much to flush.
There is increasing number of people having problems with
printk-related softlockups. We might eventually need to get better
solution. Anyway, this looks like a good start and promising
direction.
- Do not allow to schedule in console_unlock() called from printk():
This reverts an older controversial commit. The reschedule helped
to avoid softlockups. But it also slowed down the console output.
This patch is obsoleted by the new console waiter logic described
above. In fact, the reschedule made the hand-off less effective.
- Deprecate "%pf" and "%pF" format specifier:
It was needed on ia64, ppc64 and parisc64 to dereference function
descriptors and show the real function address. It is done
transparently by "%ps" and "pS" format specifier now.
Sergey Senozhatsky found that all the function descriptors were in
a special elf section and could be easily detected.
- Remove printk_symbol() API:
It has been obsoleted by "%pS" format specifier, and this change
helped to remove few continuous lines and a less intuitive old API.
- Remove redundant memsets:
Sergey removed unnecessary memset when processing printk.devkmsg
command line option.

Pull tracing updates from Steven Rostedt:
"There's not much changes for the tracing system this release. Mostly
small clean ups and fixes.
The biggest change is to how bprintf works. bprintf is used by
trace_printk() to just save the format and args of a printf call, and
the formatting is done when the trace buffer is read. This is done to
keep the formatting out of the fast path (this was recommended by
you). The issue is when arguments are de-referenced.
If a pointer is saved, and the format has something like "%*pbl", when
the buffer is read, it will de-reference the argument then. The
problem is if the data no longer exists. This can cause the kernel to
oops.
The fix for this was to make these de-reference pointes do the
formatting at the time it is called (the fast path), as this
guarantees that the data exists (and doesn't change later)"

print_req_error: I/O error, dev nvme0n1, sector 847167488
Decoding the assembly, the request claims to have 0xffff segments,
while nvme counts two. This turns out to be because we don't check
for a data carrying request on the mq scheduler path, and since
blk_phys_contig_segment() returns true for a non-data request,
we decrement the initial segment count of 0 and end up with
0xffff in the unsigned short.
There are a few issues here:
1) We should initialize the segment count for a discard to 1.
2) The discard merging is currently using the data limits for
segments and sectors.
Fix this up by having attempt_merge() correctly identify the
request, and by initializing the segment count correctly
for discards.
This can only be triggered with mq-deadline on discard capable
devices right now, which isn't a common configuration.

Merge KASAN word-at-a-time fixups from Andrey Ryabinin.
The word-at-a-time optimizations have caused headaches for KASAN, since
the whole point is that we access byte streams in bigger chunks, and
KASAN can be unhappy about the potential extra access at the end of the
string.
We used to have a horrible hack in dcache, and then people got
complaints from the strscpy() case. This fixes it all up properly, by
adding an explicit helper for the "access byte stream one word at a
time" case.
* emailed patches from Andrey Ryabinin <aryabinin@virtuozzo.com>:
fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports"
fs/dcache: Use read_word_at_a_time() in dentry_string_cmp()
lib/strscpy: Shut up KASAN false-positives in strscpy()
compiler.h: Add read_word_at_a_time() function.
compiler.h, kasan: Avoid duplicating __read_once_size_nocheck()

kasan's reports"
This reverts commit df4c0e36f1b1782b0611a77c52cc240e5c4752dd.
It's no longer needed since dentry_string_cmp() now uses
read_word_at_a_time() to avoid kasan's reports.

dentry_string_cmp() performs the word-at-a-time reads from 'cs' and may
read slightly more than it was requested in kmallac(). Normally this
would make KASAN to report out-of-bounds access, but this was
workarounded by commit df4c0e36f1b1 ("fs: dcache: manually unpoison
dname after allocation to shut up kasan's reports").
This workaround is not perfect, since it allows out-of-bounds access to
dentry's name for all the code, not just in dentry_string_cmp().
So it would be better to use read_word_at_a_time() instead and revert
commit df4c0e36f1b1.

strscpy() performs the word-at-a-time optimistic reads. So it may may
access the memory past the end of the object, which is perfectly fine
since strscpy() doesn't use that (past-the-end) data and makes sure the
optimistic read won't cross a page boundary.
Use new read_word_at_a_time() to shut up the KASAN.
Note that this potentially could hide some bugs. In example bellow,
stscpy() will copy more than we should (1-3 extra uninitialized bytes):
char dst[8];
char *src;
src = kmalloc(5, GFP_KERNEL);
memset(src, 0xff, 5);
strscpy(dst, src, 8);

Sometimes we know that it's safe to do potentially out-of-bounds access
because we know it won't cross a page boundary. Still, KASAN will
report this as a bug.
Add read_word_at_a_time() function which is supposed to be used in such
cases. In read_word_at_a_time() KASAN performs relaxed check - only the
first byte of access is validated.

Restore an optimization removed in commit 7f19449553 "Fix debugfs glocks
dump": keep the glock hash table iterator active while the glock dump
file is held open. This avoids having to rescan the hash table from the
start for each read, with quadratically rising runtime.
In addition, use rhastable_walk_peek for resuming a glock dump at the
current position: when a glock doesn't fit in the provided buffer
anymore, the next read must revisit the same glock.
Finally, also restart the dump from the first entry when we notice that
the hash table has been resized in gfs2_glock_seq_start.

Depend on LIBCRC32C which uses the crypto API to select the appropriate
crc32c implementation. With the CRYPTO and CRYPTO_CRC32C dependencies,
gfs2 would still need to use the crypto API directly like ext4 and btrfs
do, which isn't necessary.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO updates from Greg KH:
"Here is the big Staging and IIO driver patches for 4.16-rc1.
There is the normal amount of new IIO drivers added, like all
releases.
The networking IPX and the ncpfs filesystem are moved into the staging
tree, as they are on their way out of the kernel due to lack of use
anymore.
The visorbus subsystem finall has started moving out of the staging
tree to the "real" part of the kernel, and the most and fsl-mc
codebases are almost ready to move out, that will probably happen for
4.17-rc1 if all goes well.
Other than that, there is a bunch of license header cleanups in the
tree, along with the normal amount of coding style churn that we all
know and love for this codebase. I also got frustrated at the
Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
huge chunks of it that were never even being used.
Full details of everything is in the shortlog.
All of these patches have been in linux-next for a while with no
reported issues"

gcc versions prior to 4.6 require an extra level of braces when using a

This caused a compile error with the 'struct qstr' initialization in
__fscrypt_encrypt_symlink().
