Pull libnvdimm fixes from Dan Williams:
"1) Fixes for a handful of smatch reports (Thanks Dan C.!) and minor
bug fixes (patches 1-6)
2) Correctness fixes to the BLK-mode nvdimm driver (patches 7-10).
Granted these are slightly large for a -rc update. They have been
out for review in one form or another since the end of May and were
deferred from the merge window while we settled on the "PMEM API"
for the PMEM-mode nvdimm driver (ie memremap_pmem, memcpy_to_pmem,
and wmb_pmem).
Now that those apis are merged we implement them in the BLK driver
to guarantee that mmio aperture moves stay ordered with respect to
incoming read/write requests, and that writes are flushed through
those mmio-windows and platform-buffers to be persistent on media.
These pass the sub-system unit tests with the updates to
tools/testing/nvdimm, and have received a successful build-report from
the kbuild robot (468 configs).
With acks from Rafael for the touches to drivers/acpi/"

The s390-specific virtio drivers have probably more to do with virtio
than with kvm today; let's move them out into a separate section to
reflect this and to be able to add relevant mailing lists.

An abstraction layer was added to allow the hardware and clients to be
easily added. This required rewriting the NTB transport layer for this
abstraction layer. This modification will allow future
"high performance" NTB clients.
In addition to this change, a number of performance modifications were
added. These changes include NUMA enablement, using CPU memcpy instead
of asyncdma, and modification of NTB layer MTU size.

Pull fuse updates from Miklos Szeredi:
"This is the start of improving fuse scalability.
An input queue and a processing queue is split out from the monolithic
fuse connection, each of those having their own spinlock. The end of
the patchset adds the ability to clone a fuse connection. This means,
that instead of having to read/write requests/answers on a single fuse
device fd, the fuse daemon can have multiple distinct file descriptors
open. Each of those can be used to receive requests and send answers,
currently the only constraint is that a request must be answered on
the same fd as it was read from.
This can be extended further to allow binding a device clone to a
specific CPU or NUMA node.
Based on a patchset by Srinivas Eeda and Ashish Samant. Thanks to
Ashish for the review of this series"

4 drivers / enabling modules:
NFIT:
Instantiates an "nvdimm bus" with the core and registers memory devices
(NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface
table). After registering NVDIMMs the NFIT driver then registers
"region" devices. A libnvdimm-region defines an access mode and the
boundaries of persistent memory media. A region may span multiple
NVDIMMs that are interleaved by the hardware memory controller. In
turn, a libnvdimm-region can be carved into a "namespace" device and
bound to the PMEM or BLK driver which will attach a Linux block device
(disk) interface to the memory.
PMEM:
Initially merged in v4.1 this driver for contiguous spans of persistent
memory address ranges is re-worked to drive PMEM-namespaces emitted by
the libnvdimm-core. In this update the PMEM driver, on x86, gains the
ability to assert that writes to persistent memory have been flushed all
the way through the caches and buffers in the platform to persistent
media. See memcpy_to_pmem() and wmb_pmem().
BLK:
This new driver enables access to persistent memory media through "Block
Data Windows" as defined by the NFIT. The primary difference of this
driver to PMEM is that only a small window of persistent memory is
mapped into system address space at any given point in time. Per-NVDIMM
windows are reprogrammed at run time, per-I/O, to access different
portions of the media. BLK-mode, by definition, does not support DAX.
BTT:
This is a library, optionally consumed by either PMEM or BLK, that
converts a byte-accessible namespace into a disk with atomic sector
update semantics (prevents sector tearing on crash or power loss). The
sinister aspect of sector tearing is that most applications do not know
they have a atomic sector dependency. At least today's disk's rarely
ever tear sectors and if they do one almost certainly gets a CRC error
on access. NVDIMMs will always tear and always silently. Until an
application is audited to be robust in the presence of sector-tearing
the usage of BTT is recommended.

Pull cgroup updates from Tejun Heo:
- threadgroup_lock got reorganized so that its users can pick the
actual locking mechanism to use. Its only user - cgroups - is
updated to use a percpu_rwsem instead of per-process rwsem.
This makes things a bit lighter on hot paths and allows cgroups to
perform and fail multi-task (a process) migrations atomically.
Multi-task migrations are used in several places including the
unified hierarchy.
- Delegation rule and documentation added to unified hierarchy. This
will likely be the last interface update from the cgroup core side
for unified hierarchy before lifting the devel mask.
- Some groundwork for the pids controller which is scheduled to be
merged in the coming devel cycle.
