[PULL 00/28] KVM/ARM Changes for v4.16

[Christoffer Dall]

Hi Paolo and Radim,

Apologies for getting this pull request to you rather late; there were a
number of issues that I wanted to make sure we could fix properly before
including some of the changes in this pull request.

The changes for this version include icache invalidation optimizations
(improving VM startup time), support for forwarded level-triggered
interrupts (improved performance for timers and passthrough platform
devices), a small fix for power-management notifiers, and some cosmetic
changes.

The following changes since commit 50c4c4e268a2d7a3e58ebb698ac74da0de40ae36:

  Linux 4.15-rc3 (2017-12-10 17:56:26 -0800)

are available in the git repository at:
