Pull KVM fixes from Radim Krčmář:
"ARM:
- Fix handling of the 32bit cycle counter

- Amend oversight in kvm_arch_set_irq that turned Hyper-V code dead

- Do not rely on deferred update in KVM_GET_CLOCK, which fixes #GP

didn't provide means to let guests take advantage of it"

Userspace can read the exact value of kvmclock by reading the TSC
and fetching the timekeeping parameters out of guest memory. This
however is brittle and not necessary anymore with KVM 4.11. Provide
a mechanism that lets userspace know if the new KVM_GET_CLOCK
semantics are in effect, and---since we are at it---if the clock
is stable across all VCPUs.

This attempted to fix userspace breakage that no longer existed when
the patch was merged. Almost one year earlier, commit 70ba07b675b5

pkey_set() and pkey_get() were syscalls present in older versions
of the protection keys patches. They were fully excised from the
x86 code, but some cruft was left in the generic syscall code. The
C++ comments were intended to help to make it more glaring to me to
fix them before actually submitting them. That technique worked,
but later than I would have liked.
I test-compiled this for arm64.

Pull XFS support for shared data extents from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle. This
pullreq contains the new shared data extents feature for XFS.
Given the complexity and size of this change I am expecting - like the
addition of reverse mapping last cycle - that there will be some
follow-up bug fixes and cleanups around the -rc3 stage for issues that
I'm sure will show up once the code hits a wider userbase.
What it is:
At the most basic level we are simply adding shared data extents to
XFS - i.e. a single extent on disk can now have multiple owners. To do
this we have to add new on-disk features to both track the shared
extents and the number of times they've been shared. This is done by
the new "refcount" btree that sits in every allocation group. When we
share or unshare an extent, this tree gets updated.
Along with this new tree, the reverse mapping tree needs to be updated
to track each owner or a shared extent. This also needs to be updated
ever share/unshare operation. These interactions at extent allocation
and freeing time have complex ordering and recovery constraints, so
there's a significant amount of new intent-based transaction code to
ensure that operations are performed atomically from both the runtime
and integrity/crash recovery perspectives.
We also need to break sharing when writes hit a shared extent - this
is where the new copy-on-write implementation comes in. We allocate
new storage and copy the original data along with the overwrite data
into the new location. We only do this for data as we don't share
metadata at all - each inode has it's own metadata that tracks the
shared data extents, the extents undergoing CoW and it's own private
extents.
Of course, being XFS, nothing is simple - we use delayed allocation
for CoW similar to how we use it for normal writes. ENOSPC is a
significant issue here - we build on the reservation code added in
4.8-rc1 with the reverse mapping feature to ensure we don't get
spurious ENOSPC issues part way through a CoW operation. These
mechanisms also help minimise fragmentation due to repeated CoW
operations. To further reduce fragmentation overhead, we've also
introduced a CoW extent size hint, which indicates how large a region
we should allocate when we execute a CoW operation.
With all this functionality in place, we can hook up .copy_file_range,
.clone_file_range and .dedupe_file_range and we gain all the
capabilities of reflink and other vfs provided functionality that
enable manipulation to shared extents. We also added a fallocate mode
that explicitly unshares a range of a file, which we implemented as an
explicit CoW of all the shared extents in a file.
As such, it's a huge chunk of new functionality with new on-disk
format features and internal infrastructure. It warns at mount time as
an experimental feature and that it may eat data (as we do with all
new on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time the kernel
with this code in it is released.
The new code causes 5-6 new failures with xfstests - these aren't
serious functional failures but things the output of tests changing
slightly due to perturbations in layouts, space usage, etc. OTOH,
we've added 150+ new tests to xfstests that specifically exercise this
new functionality so it's got far better test coverage than any
functionality we've previously added to XFS.
Darrick has done a pretty amazing job getting us to this stage, and
special mention also needs to go to Christoph (review, testing,
improvements and bug fixes) and Brian (caught several intricate bugs
during review) for the effort they've also put in.
Summary:
- unshare range (FALLOC_FL_UNSHARE) support for fallocate
- copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr
interface
- shared extent support for XFS
- copy-on-write support for shared extents
- copy_file_range support

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"Aside from the recently added pmem sub-division support these have
been in -next for several releases with no reported issues. The sub-
division support was included in next-20161010 with no reported
issues. It passes all unit tests including new tests for all the new
functionality below.
Summary:
- PMEM sub-division support: Allow a single PMEM region to be divided
into multiple namespaces. Originally, ~2 years ago, it was thought
that partitions of a /dev/pmemX block device could handle
sub-allocations of persistent memory for different use cases. With
the decision to not support DAX mappings of raw block-devices, and
the genesis of device-dax, the need for having multiple
pmem-namespace per region has grown.
- Device-DAX unified inode: In support of dynamic-resizing of a
device-dax instance the kernel arranges for all mappings of a
device-dax node to share the same inode. This allows unmap /
truncate / invalidation events to affect all instances of the
device similar to the behavior of mmap on block devices.
- Hardware error scrubbing reworks: The original address-range-scrub
and badblocks tracking solution allowed clearing entries at the
individual namespace level, but it failed to clear the internal
list of media errors maintained at the bus level. The result was
that the next scrub or namespace disable/re-enable event would
restore the cleared badblocks, but now that is fixed. The v4.8
kernel introduced an auto-scrub-on-machine-check behavior to
repopulate the badblocks list. Now, in v4.9, the auto-scrub
behavior can be disabled and simply arrange for the error reported
in the machine-check to be added to the list.
- DIMM health-event notification support: ACPI 6.1 defines a
notification event code that can be send to ACPI NVDIMM devices. A
poll(2) capable file descriptor for these events can be obtained
from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory
device.
- Miscellaneous fixes: NVDIMM-N probe error, device-dax build error,
and a change to dedup the flush hint list to not flush the memory
controller more than necessary"

We had inserted a #error into the topology UAPI code to ensure that the
ABI was not adopted by userspace while final review and testing was
ongoing. The idea was that some finishing touches would be made to the
ABI before declaring it stable and suitable for use in production but
this has not yet happened as more than a year later revisions to the ABI
are still onging.
The reality however is that people are shipping topology files in
production and these ABI changes are causing practical issues for users
and we can't break userspace. This makes this error pointless so we
should remove it.

Pull SCSI updates from James Bottomley:
"This update includes the usual round of major driver updates (hpsa,
be2iscsi, hisi_sas, zfcp, cxlflash). There's a new incarnation of hpsa
called smartpqi for which a driver is added, there's some cleanup work
of the ibm vscsi target and updates to libfc, plus a whole host of
minor fixes and updates and finally the removal of several ISA drivers
which seem not to have been used for years"
