This is a small patch series that I accumulated while tracking what
turned out to be an unrelated issue.

The first patch has already been posted a while ago and included here
for completeness. The others are fairly simple missing barriers/clear
exclusives that are actually required.

This has been tested on TC2, and is also available in my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm/fixes-3.10-rc6

>From v1:
- Dropped two barrier related patches after Will convinced me that they
  were not required at all.
- Changed dsb to "dsb ishst" in the second patch to reflect that we only
  care about stores.

Marc Zyngier (3):
  ARM: KVM: perform save/restore of PAR
  ARM: KVM: add missing dsb before invalidating Stage-2 TLBs
  ARM: KVM: clear exclusive monitor on all exception returns
