Cosmetic only -- no functional change in this patch.
sysfs before:
state4/desc:MWAIT 0x20
state4/name:C6-HSW
sysfs after:
state4/desc:MWAIT 0x20
state4/name:C6
We remove the platform acronyms from the end of the state name
(-HSW in this case) for three reasonse.
1. more consistency with acpi_idle, which prints C1, C2, C3 etc.
2. users know what platform they are on already
an acronym for the processor code name here
seems to cause more confusion than clarity.
3. less clutter in "cpupower monitor" output,
which truncates the names to 4 columns.
The precise definition of the state continues to be available in "desc".

Pull ceph updates from Ilya Dryomov:
"This time around we have:
- support for rbd data-pool feature, which enables rbd images on
erasure-coded pools (myself). CEPH_PG_MAX_SIZE has been bumped to
allow erasure-coded profiles with k+m up to 32.
- a patch for ceph_d_revalidate() performance regression introduced
in 4.9, along with some cleanups in the area (Jeff Layton)
- a set of fixes for unsafe ->d_parent accesses in CephFS (Jeff
Layton)
- buffered reads are now processed in rsize windows instead of rasize
windows (Andreas Gerstmayr). The new default for rsize mount option
is 64M.
- ack vs commit distinction is gone, greatly simplifying ->fsync()
and MOSDOpReply handling code (myself)
... also a few filesystem bug fixes from Zheng, a CRUSH sync up (CRUSH
computations are still serialized though) and several minor fixes and
cleanups all over"

This version bump reflects that the reshape corruption fix (commit
92a39f6cc "dm raid: fix data corruption on reshape request") is
present.
Done as a separate fix because the above referenced commit is marked for
stable and target version bumps in a stable@ fix are a recipe for the
fix to never get backported to stable@ kernels (because of target
version number conflicts).
Also, move RESUME_STAY_FROZEN_FLAGS up with the reset the the _FLAGS
definitions now that we don't need to worry about stable@ conflicts as a
result of missing context.

The lvm2 sequence to manage dm-raid constructor flags that trigger a
rebuild or a reshape is defined as:
1) load table with flags (e.g. rebuild/delta_disks/data_offset)
2) clear out the flags in lvm2 metadata
3) store the lvm2 metadata, reload the table to reset the flags
previously established during the initial load (1) -- in order to
prevent repeatedly requesting a rebuild or a reshape on activation
Currently, loading an inactive table with rebuild/reshape flags
specified will cause dm-raid to rebuild/reshape on resume and thus start
updating the raid metadata (about the progress). When the second table
reload, to reset the flags, occurs the constructor accesses the volatile
progress state kept in the raid superblocks. Because the active mapping
is still processing the rebuild/reshape, that position will be stale by
the time the device is resumed.
In the reshape case, this causes data corruption by processing already
reshaped stripes again. In the rebuild case, it does _not_ cause data
corruption but instead involves superfluous rebuilds.
Fix by keeping the raid set frozen during the first resume and then
allow the rebuild/reshape during the second resume.

While cleaning up awkward branching in raid_message() a raid set "check"
regression was introduced because "check" needs both MD_RECOVERY_SYNC
and MD_RECOVERY_REQUESTED flags set.
Fix this regression by explicitly setting both flags for the "check"
case (like is also done for the "repair" case, but redundant set_bit()s
are perfectly fine because it adds clarity to what is needed in response
to both messages -- in addition this isn't fast path code).

There is a problem with intel_pstate operation mode switching
introduced by commit fb1fe1041c04 (cpufreq: intel_pstate: Operation
mode control from sysfs), because the global sysfs limits are
preserved across operation modes while per-policy limits are
reinitialized from scratch on a mode switch and both sets of limits
may get out of sync this way.
Fix that by always reinitializing the global limits upon the
registration of the driver.

Pull cgroup updates from Tejun Heo:
"Several noteworthy changes.
- Parav's rdma controller is finally merged. It is very straight
forward and can limit the abosolute numbers of common rdma
constructs used by different cgroups.
- kernel/cgroup.c got too chubby and disorganized. Created
kernel/cgroup/ subdirectory and moved all cgroup related files
under kernel/ there and reorganized the core code. This hurts for
backporting patches but was long overdue.
- cgroup v2 process listing reimplemented so that it no longer
depends on allocating a buffer large enough to cache the entire
result to sort and uniq the output. v2 has always mangled the sort
order to ensure that users don't depend on the sorted output, so
this shouldn't surprise anybody. This makes the pid listing
functions use the same iterators that are used internally, which
have to have the same iterating capabilities anyway.
- perf cgroup filtering now works automatically on cgroup v2. This
patch was posted a long time ago but somehow fell through the
cracks.
- misc fixes asnd documentation updates"

The ast driver configures a window to enable access into BMC
memory space in order to read some configuration registers.
If this window is disabled, which it can be from the BMC side,
the ast driver can't function.
Closing this window is a necessity for security if a machine's
host side and BMC side are controlled by different parties;
i.e. a cloud provider offering machines "bare metal".
A recent patch went in to try to check if that window is open
but it does so by trying to access the registers in question
and testing if the result is 0xffffffff.
This method will trigger a PCIe error when the window is closed
which on some systems will be fatal (it will trigger an EEH
for example on POWER which will take out the device).
This patch improves this in two ways:
- First, if the firmware has put properties in the device-tree
containing the relevant configuration information, we use these.
- Otherwise, a bit in one of the SCU scratch registers (which
are readable via the VGA register space and writeable by the BMC)
will indicate if the BMC has closed the window. This bit has been
defined by Y.C Chen from Aspeed.
If the window is closed and the configuration isn't available from
the device-tree, some sane defaults are used. Those defaults are
hopefully sufficient for standard video modes used on a server.

printk has a special "%pad" format string that passes the dma address by
reference to solve this problem.

The new debugfs output causes a link error on 32-bit architectures:
ERROR: "__aeabi_uldivmod" [drivers/scsi/lpfc/lpfc.ko] undefined!
This code is not performance critical, so we can simply use div_u64().

We already have the helper, we can convert the rest of the kernel
mechanically using:
git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/'
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

Fix typos and add the following to the scripts/spelling.txt:
followings||following
While we are here, add a missing colon in the boilerplate in DT binding
documents. The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as
well.
I reworded "as the followings:" to "as follows:" for
drivers/usb/gadget/udc/renesas_usb3.c.
