KVM: MMU: increase per-vcpu rmap cache alloc size
The page fault path can use two rmap_desc structures, if: - walk_addr's dirty pte update allocates one rmap_desc. - mmu_lock is dropped, sptes are zapped resulting in rmap_desc being freed. - fetch->mmu_set_spte allocates another rmap_desc. Increase to 4 for safety. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
