KVM: MMU: Fix setting the accessed bit on non-speculative sptes
(cherry picked from commit 3201b5d9f0f7ef392886cd76dcd2c69186d9d5cd) The accessed bit was accidentally turned on in a random flag word, rather than, the spte itself, which was lucky, since it used the non-EPT compatible PT_ACCESSED_MASK. Fix by turning the bit on in the spte and changing it to use the portable accessed mask. Signed-off-by: Avi Kivity <avi@qumranet.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
