Linus Torvalds 8546dc1d4b Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "The major items included in here are:

   - MCPM, multi-cluster power management, part of the infrastructure
     required for ARMs big.LITTLE support.

   - A rework of the ARM KVM code to allow re-use by ARM64.

   - Error handling cleanups of the IS_ERR_OR_NULL() madness and fixes
     of that stuff for arch/arm

   - Preparatory patches for Cortex-M3 support from Uwe Kleine-König.

  There is also a set of three patches in here from Hugh/Catalin to
  address freeing of inappropriate page tables on LPAE.  You already
  have these from akpm, but they were already part of my tree at the
  time he sent them, so unfortunately they'll end up with duplicate
  commits"

Marc Zyngier 6190920a35 ARM: KVM: move kvm_handle_wfi to handle_exit.c
It has little to do in emulate.c these days...

Christoffer Dall c088f8f008 KVM: ARM: Reintroduce trace_kvm_hvc
This one got lost in the move to handle_exit, so let's reintroduce it
using an accessor to the immediate value field like the other ones.

Marc Zyngier 3414bbfff9 ARM: KVM: move exit handler selection to a separate file
The exit handler selection code cannot be shared with arm64
(two different modes, more exception classes...).

Move it to a separate file (handle_exit.c).
