Merge tag 'kvm-arm-fixes-4.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into 'kvm-next'
Fixes for KVM/ARM for 4.0-rc5. Fixes page refcounting issues in our Stage-2 page table management code, fixes a missing unlock in a gicv3 error path, and fixes a race that can cause lost interrupts if signals are pending just prior to entering the guest.
