Please don't base series on prerequisite patches unless there is a hard dependency.

  ffdc6a9d6d9eb20c855404e2c09b6b2ea25b4a04 KVM: selftests: Rename $(ARCH_DIR) to $(SRCARCH)

By all means, do testing on top of such patches if that's what your environment
effectively dictates, but rebase/drop such prereqs before posting, as they add
noise and friction.  E.g. these patches don't apply cleanly on kvm-x86/next due
to the prereqs.
