The mmc_read_ssr() function results in DMA to the raw_ssr member of
struct mmc_card, which is not guaranteed to be cache line aligned & thus
might not meet the requirements set out in Documentation/DMA-API.txt:

  Warnings:  Memory coherency operates at a granularity called the cache
  line width.  In order for memory mapped by this API to operate
  correctly, the mapped region must begin exactly on a cache line
  boundary and end exactly on one (to prevent two separately mapped
  regions from sharing a single cache line).  Since the cache line size
  may not be known at compile time, the API will not enforce this
  requirement.  Therefore, it is recommended that driver writers who
  don't take special care to determine the cache line size at run time
  only map virtual regions that begin and end on page boundaries (which
  are guaranteed also to be cache line boundaries).

On some systems where DMA is non-coherent this can lead to us losing
data that shares cache lines with the raw_ssr array.

Fix this by kmalloc'ing a temporary buffer to perform DMA into. kmalloc
will ensure the buffer is suitably aligned, allowing the DMA to be
performed without any loss of data.

Commit e0097cf5 ("mmc: queue: Fix queue thread wake-up") did not go far
enough. mmc_wait_for_data_req_done() still contains some problems and can
be further simplified.  First it should not touch
context_info->is_waiting_last_req because that is a wake-up control used by
the owner of the context. Secondly, it should always return when one of its
wake-up conditions is met because, again, that is contolled by the owner of
the context.

While the current block driver does not have an issue, these problems were
exposed during testing of the Software Command Queue patches.

dquot_disable() was warning when sb_has_quota_loaded() was true when
invalidating page cache for quota files. The thinking behind this
warning was that we must have raced with somebody else turning quotas on
and this should not happen because all places modifying quota state must
hold s_umount exclusively now. However sb_has_quota_loaded() can be also
true at this point when we are just suspending quotas on remount
read-only. Just restore the behavior to situation before commit
c3b00446 ("quota: Remove dqonoff_mutex") which introduced the
warning.

According to Microchip errata some combinations of date and month
values may result in the date being reset to 1, even if the date
is also written with the month (for example 31-07 or 31-08).
As a workaround avoid writing date and month values within the same
Write command. Instead, terminate the Write command after loading
the date and begin a new command to write the month. In addition,
disable the oscillator before loading the new values. This is done
by ensuring both the ST and EXTOSC bits are cleared and waiting for
the OSCON bit to clear.

Pull libnvdimm updates from Dan Williams:
 "The libnvdimm pull request is relatively small this time around due to
  some development topics being deferred to 4.11.

  As for this pull request the bulk of it has been in -next for several
  releases leading to one late fix being added (commit 868f036f
  ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It
  has received a build success notification from the 0day-kbuild robot
  and passes the latest libnvdimm unit tests.

  Summary:

   - Dynamic label support: To date namespace label support has been
     limited to disambiguating cases where PMEM (direct load/store) and
     BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since
     4.9 added support for multiple namespaces per PMEM-region there is
     value to support namespace labels even in the non-aliasing case.
     The presence of a valid namespace index block force-enables label
     support when the kernel would otherwise rely on region boundaries,
     and permits the region to be sub-divided.

   - Handle media errors in namespace metadata: Complement the error
     handling for media errors in namespace data areas with support for
     clearing errors on writes, and downgrading potential machine-check
     exceptions to simple i/o errors on read.

   - Device-DAX region attributes: Add 'align', 'id', and 'size' as
     attributes for device-dax regions. In particular this enables
     userspace tooling to generically size memory mapping and i/o
     operations. Prevent userspace from growing assumptions /
     dependencies about the parent device topology for a dax region. A
     libnvdimm namespace may not always be the parent device of a dax
     region.

   - Various cleanups and small fixes"

Pull timer updates from Thomas Gleixner:
 "This is the last functional update from the tip tree for 4.10. It got
  delayed due to a newly reported and anlyzed variant of BIOS bug and
  the resulting wreckage:

   - Seperation of TSC being marked realiable and the fact that the
     platform provides the TSC frequency via CPUID/MSRs and making use
     for it for GOLDMONT.

   - TSC adjust MSR validation and sanitizing:

     The TSC adjust MSR contains the offset to the hardware counter. The
     sum of the adjust MSR and the counter is the TSC value which is
     read via RDTSC.

     On at least two machines from different vendors the BIOS sets the
     TSC adjust MSR to negative values. This happens on cold and warm
     boot. While on cold boot the offset is a few milliseconds, on warm
     boot it basically compensates the power on time of the system. The
     BIOSes are not even using the adjust MSR to set all CPUs in the
     package to the same offset. The offsets are different which renders
     the TSC unusable,

     What's worse is that the TSC deadline timer has a HW feature^Wbug.
     It malfunctions when the TSC adjust value is negative or greater
     equal 0x80000000 resulting in silent boot failures, hard lockups or
     non firing timers. This looks like some hardware internal 32/64bit
     issue with a sign extension problem. Intel has been silent so far
     on the issue.

     The update contains sanity checks and keeps the adjust register
     within working limits and in sync on the package.

     As it looks like this disease is spreading via BIOS crapware, we
     need to address this urgently as the boot failures are hard to

Adjust value 0x80000000 and other values larger than that render the TSC
deadline timer disfunctional.

We have not yet any information about this from Intel, but experimentation
clearly proves that this is a 32/64 bit and sign extension issue.

If adjust values larger than that are actually required, which might be the
case for physical CPU hotplug, then we need to disable the deadline timer
on the affected package/CPUs and use the local APIC timer instead.

That requires some surgery in the APIC setup code, so we just limit the
ADJUST register value into the known to work range for now and revisit this
when Intel comes forth with proper information.

Merge uncontroversial parts of branch 'readlink' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs

Pull partial readlink cleanups from Miklos Szeredi.

This is the uncontroversial part of the readlink cleanup patch-set that
simplifies the default readlink handling.

Miklos and Al are still discussing the rest of the series.

* git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
  vfs: make generic_readlink() static
  vfs: remove ".readlink = generic_readlink" assignments
  vfs: default to generic_readlink()
  vfs: replace calling i_op->readlink with vfs_readlink()
  proc/self: use generic_readlink
  ecryptfs: use vfs_get_link()
  bad_inode: add missing i_op initializers

The build of sparc allmodconfig fails with the error:
"of_irq_to_resource" [drivers/net/ethernet/marvell/mv643xx_eth.ko]
	undefined!

of_irq_to_resource() is defined when CONFIG_OF_IRQ is defined. And also
CONFIG_OF_IRQ can only be defined if CONFIG_IRQ is defined. So we can
safely use #if defined(CONFIG_OF_IRQ) in the code.

The coming initify gcc plugin expects const pointer types, and caught
some __printf arguments that weren't const yet. This fixes those.

When a port is split we should mark it as such, as otherwise the split
ports aren't renamed correctly (e.g. sw1p3 -> sw1p3s1) and the unsplit
operation fails:

$ devlink port split sw1p3 count 4
$ devlink port unsplit eth0
devlink answers: Invalid argument
[  598.565307] mlxsw_spectrum 0000:03:00.0 eth0: Port wasn't split
