I am interested in all ASPEED drivers, and the previous match wasn't
grabbing files in nested directories. Use N instead.
Add the arm kernel mailing list so that patches get reviewed there, and
the linux-aspeed list which exists only so I can use patchwork to track
patches.
Add Andrew as a reviewer, because he is involved in reviewing ASPEED
stuff.

- support for rbd "fancy" striping (myself). The striping feature bit
is now fully implemented, allowing mapping v2 images with non-default
striping patterns. This completes support for --image-format 2.
- CephFS quota support (Luis Henriques and Zheng Yan). This set is
based on the new SnapRealm code in the upcoming v13.y.z ("Mimic")
release. Quota handling will be rejected on older filesystems.
- memory usage improvements in CephFS (Chengguang Xu). Directory
specific bits have been split out of ceph_file_info and some effort
went into improving cap reservation code to avoid OOM crashes.
Also included a bunch of assorted fixes all over the place from
Chengguang and others.

Dell SMBIOS driver fixed against memory leaks.
The fujitsu-laptop driver is cleaned up and now supports hotkeys for
Lifebook U7x7 models. Besides that the typo introduced by one of
previous clean up series has been fixed.
Specific to x86-based laptops HID device now supports
KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example,
by Wacom MobileStudio Pro 13.
Turbo MAX 3 technology is enabled for the rest of platforms that support
Hardware-P-States feature which have core priority described by
ACPI CPPC table.
Mellanox on x86 gets better support of I2C bus in use including support
of hotpluggable ones.
Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and
I.T.Works TW701.
From now on the second fan on Thinkpad P50 is supported.

Merge tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"This cycle was was not something I ever want to repeat as there were
several late changes that have only now just settled.
Half of the branch up to commit d2c997c0f1 ("fs, dax: use
page->mapping to warn...") have been in -next for several releases.
The of_pmem driver and the address range scrub rework were late
arrivals, and the dax work was scaled back at the last moment.
The of_pmem driver missed a previous merge window due to an oversight.
A sense of obligation to rectify that miss is why it is included for
4.17. It has acks from PowerPC folks. Stephen reported a build failure
that only occurs when merging it with your latest tree, for now I have
fixed that up by disabling modular builds of of_pmem. A test merge
with your tree has received a build success report from the 0day robot
over 156 configs.
An initial version of the ARS rework was submitted before the merge
window. It is self contained to libnvdimm, a net code reduction, and
passing all unit tests.
The filesystem-dax changes are based on the wait_var_event()
functionality from tip/sched/core. However, late review feedback
showed that those changes regressed truncate performance to a large
degree. The branch was rewound to drop the truncate behavior change
and now only includes preparation patches and cleanups (with full acks
and reviews). The finalization of this dax-dma-vs-trnucate work will
need to wait for 4.18.
Summary:
- A rework of the filesytem-dax implementation provides for detection
of unmap operations (truncate / hole punch) colliding with
in-progress device-DMA. A fix for these collisions remains a
work-in-progress pending resolution of truncate latency and
starvation regressions.
- The of_pmem driver expands the users of libnvdimm outside of x86
and ACPI to describe an implementation of persistent memory on
PowerPC with Open Firmware / Device tree.
- Address Range Scrub (ARS) handling is completely rewritten to

The main purpose of this pull request is a fix for a regression
in the recent PCM OSS emulation code that may lead to RCU stall.
Since syzkaller hits this too often, I send the pull request now
with a minimal collection. Possibly another pull request may
follow before RC1.
The other fixes here are for USB-audio class 2 and 3 to improve
the parser for the clock descriptors. These are rather cleanups
but good for security, too.
Last but not least, another included fix is the trivial one to
remove superfluous WARN_ON() that annoyed syzbot.

Pull media fixes from Mauro Carvalho Chehab:
"A series of media updates/fixes for 4.17.
There are two important core fix patches in this series:
- A regression fix on Kernel 4.16 with causes it to not work with
some input devices that depend on media core
- A fix at compat32 bits with causes it to OOPS on overlay, and
affects the Kernels where the CVE-2017-13166 was backported
The remaining ones are other random fixes at the documentation and on
drivers.
The biggest part of this series is a set of 18 patches for the Intel
atomisp driver. Currently, it produces hundreds of warnings/errors on
sparse/smatch, causing me to sometimes ignore new warnings on other
drivers that are not so broken. This driver is on really poor state,
even for staging standards: it has several layers of abstraction on
it, and it supports two different hardware. Selecting between them
require to add a define (there isn't even a Kconfig option for such
purpose). Just on this smatch cleanup, I could easily get rid of 8
"do-nothing" files. So, I'm seriously considering its removal from
upstream, if I don't see any real work on addressing the problems
there along this year"

This patch Enable ARM L2 cache module in Nuvoton NPCM7xx BMC
by adding L2 cache parameters into NPCM7xx DT machine start structure.
At patch V7 arm: npcm: add basic support for Nuvoton BMCs we got comments
regarding the flags use in L2 cache module.
- https://www.spinics.net/lists/arm-kernel/msg613212.html
After checking again the L2 cache use in the NPCM7xx,
the only L2 cache flag we need to set is L2C_AUX_CTRL_SHARED_OVERRIDE
and it is done in the device tree:

c6x depends on the macro '_BIG_ENDIAN' being defined or not
to correctly select or define endian-specific macros, structures
or pieces of code.
This macro is predefined by the compiler but sparse knows nothing
about it and thus may pre-process files differently from what
gcc would.
Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian
kernel, like GCC would have done.

The use of bitfields seems to confuse gcc, leading to a false-positive
warning in all compiler versions:
kernel/time/tick-sched.c: In function 'tick_nohz_idle_exit':
kernel/time/tick-sched.c:538:2: error: 'now' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This introduces a temporary variable to track the flags so gcc
doesn't have to evaluate twice, eliminating the code path that
leads to the warning.

When multiple CPUs are related in one cpufreq policy, the first online
CPU will be chosen by default to handle cpufreq operations. Let's take
cpu0 and cpu1 as an example.
When cpu0 is offline, policy->cpu will be shifted to cpu1. cpu1's perf
capabilities should be initialized. Otherwise, perf capabilities are 0s
and speed change can not take effect.
This patch copies perf capabilities of the first online CPU to other
shared CPUs when policy shared type is CPUFREQ_SHARED_TYPE_ANY.

Commit 3c8ba0d61d ("kernel.h: Retain constant expression output for
max()/min()") rewrote our min/max macros to be very clever, but in the
meantime resurrected a variable name shadow issue that we had had
previously fixed in commit 589a9785ee ("min/max: remove sparse
warnings when they're nested").
That commit talks about the sparse warnings that this shadowing causes,
which we ignored as just a minor annoyance. But it turns out that the
sparse warning is the least of our problems. We actually have a real
bug due to the shadowing through the interaction with "min_not_zero()",
which ends up doing
min(__x, __y)
internally, and then the new declaration of "__x" and "__y" as new
variables in __cmp_once() results in a complete mess of an expression,
and "min_not_zero()" doesn't work at all.
For some odd reason, this only ever caused (reported) problems on s390,
even though it is a generic issue and most of the (obviously successful)
testing of the problematic commit had happened on other architectures.
Quoting Sebastian Ott:
"What happened is that the bio build by the partition detection code
was attempted to be split by the block layer because the block queue
had a max_sector setting of 0. blk_queue_max_hw_sectors uses
min_not_zero."
So re-introduce the use of __UNIQUE_ID() to make sure that the min/max
macros do not have these kinds of clashes.
[ That said, __UNIQUE_ID() itself has several issues that make it less
than wonderful.
In particular, the "uniqueness" has a fallback on the line number,
which means that it's not actually unique in more complex cases if you
don't build with gcc or clang (which have working unique counters that
aren't tied to line numbers).
That historical broken fallback also means that we have that pointless
"prefix" argument that doesn't actually make much sense _except_ for
the known-broken case. Oh well. ]
