Pull s390 updates from Martin Schwidefsky:
 "The big one is support for fake NUMA, splitting a really large machine
  in more manageable piece improves performance in some cases, e.g. for
  a KVM host.

  The FICON Link Incident handling has been improved, this helps the
  operator to identify degraded or non-operational FICON connections.

  The save and restore of floating point and vector registers has been
  overhauled to allow the future use of vector registers in the kernel.

  A few small enhancement, magic sys-requests for the vt220 console via
  SCLP, some more assembler code has been converted to C, the PCI error
  handling is improved.

  And the usual cleanup and bug fixing"

Pull nvdimm fixlet from Dan Williams:
 "This is a libnvdimm ABI fixup.

  I pushed back on this change quite hard given the late date, that it
  appears to be purely cosmetic, sysfs is not necessarily meant to be a
  user friendly UI, and the kernel interprets the reversed polarity of
  the ACPI_NFIT_MEM_ARMED flag correctly.  When this flag is set, the
  energy source of an NVDIMM is not armed and any new writes to the DIMM
  may not be preserved.

  However, Bob Moore warned me that it is important to get these things
  named correctly wherever they appear otherwise we run the risk of a
  less than cautious firmware engineer implementing the polarity the
  wrong way.  Once a mistake like that escapes into production platforms
  the flag becomes useless and we need to move to a new bit position.

  Bob has agreed to take a change through ACPICA to rename
  ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below
  from Toshi brings the sysfs representation of these flags in line with
  their respective polarities.

  Please pull for 4.2 as this is the first kernel to expose the ACPI
  NFIT sysfs representation, and this is likely a kernel that firmware
  developers will be using for checking out their NVDIMM enabling"

  nfit: Clarify memory device state flags strings

Commit f8d96052 ("sctp: Enforce retransmission limit during shutdown")
fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by not
resetting the association overall_error_count.  This allowed the association
to better enforce assoc.max_retrans limit.

However, the same issue still exists when the association is in SHUTDOWN_RECEIVED
state.  In this state, HB-ACKs will continue to reset the overall_error_count
for the association would extend the lifetime of association unnecessarily.

This patch solves this by resetting the overall_error_count whenever the current
state is small then SCTP_STATE_SHUTDOWN_PENDING.  As a small side-effect, we
end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and SCTP_STATE_SHUTDOWN_SENT
states, but they are not really impacted because we disable Heartbeats in those
states.

in sctp_process_asconf(), we get address parameter from the beginning of
the addip params. but we never check if it's really there. if the addr
param is not there, it still can pass sctp_verify_asconf(), then to be
handled by sctp_process_asconf(), it will not be safe.

so add a code in sctp_verify_asconf() to check the address parameter is in
the beginning, or return false to send abort.

note that this can also detect multiple address parameters, and reject it.

ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
NVDIMM status as follows.  These bits indicate multiple info,
such as failures, pending event, and capability.

  Bit [0] set to 1 to indicate that the previous SAVE to the
  Memory Device failed.
  Bit [1] set to 1 to indicate that the last RESTORE from the
  Memory Device failed.
  Bit [2] set to 1 to indicate that platform flush of data to
  Memory Device failed. As a result, the restored data content
  may be inconsistent even if SAVE and RESTORE do not indicate
  failure.
  Bit [3] set to 1 to indicate that the Memory Device is observed
  to be not armed prior to OSPM hand off. A Memory Device is
  considered armed if it is able to accept persistent writes.
  Bit [4] set to 1 to indicate that the Memory Device observed
  SMART and health events prior to OSPM handoff.

/sys/bus/nd/devices/nmemX/nfit/flags shows this flags info.
The output strings associated with the bits are "save", "restore",
"smart", etc., which can be confusing as they may be interpreted
as positive status, i.e. save succeeded.

Change also the dev_info() message in acpi_nfit_register_dimms()
to be consistent with the sysfs flags strings.

Pull amr64 kvm fix from Will Deacon:
 "We've uncovered a nasty bug in the arm64 KVM code which allows a badly
  behaved 32-bit guest to bring down the host.  The fix is simple (it's
  what I believe we call a "brown paper bag" bug) and I don't think it
  makes sense to sit on this, particularly as Russell ended up
  triggering this rather than just somebody noticing a potential problem
  by inspection.

  Usually arm64 KVM changes would go via Paolo's tree, but he's on
  holiday at the moment and the deal is that anything urgent gets
  shuffled via the arch trees, so here it is.

  Summary:

  Fix arm64 KVM issue when injecting an abort into a 32-bit guest, which
  would lead to an illegal exception return at EL2 and a subsequent host
  crash"

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  arm64: KVM: Fix host crash when injecting a fault into a 32bit guest

When injecting a fault into a misbehaving 32bit guest, it seems
rather idiotic to also inject a 64bit fault that is only going
to corrupt the guest state. This leads to a situation where we
perform an illegal exception return at EL2 causing the host
to crash instead of killing the guest.

Just fix the stupid bug that has been there from day 1.

Pull block fixes from Jens Axboe:
 "Two fixes in this pull request:

   - The writeback regression fix from Tejun, which has been weeks in
     the making.  This fixes a case where we would sometimes not issue
     writeback when we should have.

   - An older fix for a memory corruption issue in mtip32xx.  It was
     deferred since we wanted a better fix for this (driver should not
     have to handle that case), but given the timing, it's better to put
     the simple fix in for 4.2 release"

Implement magic sysrequest handling for the VT220 terminal (also known as
the Integrated ASCII console on the HMC/SE).
To invoke a "magic sysrequest" function, press "Ctrl+o" followed by a
second character that designates the debugging function.

The handling of the sysrq is scheduled away from the SCLP IRQ context;
because large amounts of sysrq output might fill up the console buffers.
The console might deadlock because it cannot empty the buffers while still
in the receiving IRQ context.  This behavior is the same as for the SCLP
console.
