Cover letter [PATCH v2 0/3] A handful of KVM/ARM fixes
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
Quoted 1 line
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.
