KVM: MMU: kvm_pv_mmu_op should not take mmap_sem
kvm_pv_mmu_op should not take mmap_sem. All gfn_to_page() callers down in the MMU processing will take it if necessary, so as it is it can deadlock. Apparently a leftover from the days before slots_lock. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
