KVM: Allow reading aliases with mmu_lock
This allows the mmu notifier code to run unalias_gfn with only the mmu_lock held. Only alias writes need the mmu_lock held. Readers will either take the slots_lock in read mode or the mmu_lock. Signed-off-by: Andrea Arcangeli <andrea@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
