Marcelo Tosatti 6c475352e8 KVM: MMU: avoid creation of unreachable pages in the shadow ... It is possible for a shadow page to have a parent link pointing to a freed page. When zapping a high level table, kvm_mmu_page_unlink_children fails to remove the parent_pte link. For that to happen, the child must be unreachable via the shadow tree, which can happen in shadow_walk_entry if the guest pte was modified in between walk() and fetch(). Remove the parent pte reference in such case. Possible cause for oops in bug #2217430. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>		16 years ago
