Pull KVM fixes from Paolo Bonzini:
 "(Relatively) a lot of reverts, mostly.

  Bugs have trickled in for a new feature in 4.2 (MTRR support in
  guests) so I'm reverting it all; let's not make this -rc period busier
  for KVM than it's been so far.  This covers the four reverts from me.

  The fifth patch is being reverted because Radim found a bug in the
  implementation of stable scheduler clock, *but* also managed to
  implement the feature entirely without hypervisor support.  So instead
  of fixing the hypervisor side we can remove it completely; 4.4 will
  get the new implementation"

Pull rdma fixes from Doug Ledford:
 - Fixes for mlx5 related issues
 - Fixes for ipoib multicast handling

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma:
  IB/ipoib: increase the max mcast backlog queue
  IB/ipoib: Make sendonly multicast joins create the mcast group
  IB/ipoib: Expire sendonly multicast joins

  IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY
  IB/iser: Add module parameter for always register memory
  xprtrdma: Replace global lkey with lkey local to PD

The cpu feature flags are not ever going to change, so warning
everytime can cause a lot of kernel log spam
(in our case more than 10GB/hour).

The warning seems to only occur when nested virtualization is
enabled, so it's probably triggered by a KVM bug.  This is a
sensible and safe change anyway, and the KVM bug fix might not
be suitable for stable releases anyway.

As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state.  Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.

We already did this for the IPC semaphore code (see commit e8577d1f:
"ipc/sem.c: fully initialize sem_array before making it visible") but we
clearly forgot about msg and shm.

While the lockdep splat is a false positive, becuase path_openat holds i_mutex
of the parent directory and ubifs_init_security() tries to acquire i_mutex
of a new inode, it reveals that taking i_mutex in ubifs_init_security() is
in vain because it is only being called in the inode allocation path
and therefore nobody else can see the inode yet.

MAARs should be initialised on each CPU (or rather, core) in the system
in order to achieve consistent behaviour & performance. Previously they
have only been initialised on the boot CPU which leads to performance
problems if tasks are later scheduled on a secondary CPU, particularly
if those tasks make use of unaligned vector accesses where some CPUs
don't handle any cases in hardware for non-speculative memory regions.
Fix this by recording the MAAR configuration from the boot CPU and
applying it to secondary CPUs as part of their bringup.

maar_init was previously only compiled when CONFIG_NEED_MULTIPLE_NODES

move maar_init outside of the #ifndef such that it is always compiled.

gic_handle_shared_int reads the GIC interrupt pending & mask registers
directly into a bitmap, which is defined as an array of unsigned longs.
The GIC pending registers may be 32 bits wide if the CM is older than
CM3, regardless of the bit width of the CPU, but for MIPS64 kernels
the unsigned longs in the bitmap will be 64 bits wide. In this case we
need to perform 2 x 32 bit reads per 64 bit unsigned long in order to
avoid missing interrupts.

Make use of the mips_cm_vp_id function to convert from Linux CPU numbers
to the VP IDs used by hardware, which are not identical in all systems.
Without doing so we map interrupts to incorrect VP(E)s.

The VP ID of a given CPU may not match up with the CPU number used by
Linux. For example, if the width of the VP part of the VP ID is wider
than log2(number of VPs per core) and the system has multiple cores then
this will be the case. Alternatively, if a pre-r6 system implements the
MT ASE with multiple VPEs per core and Linux is built without support
for the MT ASE then the numbers won't match up either. Provide a
function to convert from CPU number to VP ID.

Pull x86 fixes from Thomas Gleixner:
 "Two bugfixes from Andy addressing at least some of the subtle NMI
  related wreckage which has been reported by Sasha Levin"

 "A bugfix for the atmel aic5 irq chip driver which caches the wrong
  data and thereby breaking resume"

Pull ARM fixes from Russell King:
 "Just two fixes: wire up the new system calls added during the last
  merge window, and fix another user access site"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: alignment: fix alignment handling for uaccess changes
  ARM: wire up new syscalls

Pull ARM SoC fixes from Olof Johansson:
 "Our first real batch of fixes this release cycle.  Nothing really
  concerning, and diffstat is a bit inflated due to some DT contents
  moving around on STi platforms.

  There's a collection of them here:

   - A fixup for a build breakage that hits on arm64 allmodconfig in
     QCOM SCM firmware drivers
   - MMC fixes for OMAP that had quite a bit of breakage this merge
     window.
   - Misc build/warning fixes on PXA and OMAP
   - A couple of minor fixes for Beagleboard X15 which is now starting
     to see a few more users in the wild"
