KVM: MMU: hypercall based pte updates and TLB flushes
Hypercall based pte updates are faster than faults, and also allow use of the lazy MMU mode to batch operations. Don't report the feature if two dimensional paging is enabled. [avi: - one mmu_op hypercall instead of one per op - allow 64-bit gpa on hypercall - don't pass host errors (-ENOMEM) to guest] [akpm: warning fix on i386] Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Avi Kivity <avi@qumranet.com>
