KVM: MMU: cleanup for FNAME(fetch)
gw->pte_access is the final access permission, since it is unified with gw->pt_access when we walked guest page table: FNAME(walk_addr_generic): pte_access = pt_access & FNAME(gpte_access)(vcpu, pte, true); Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
