KVM: MMU: drop zeroing on mmu_memory_cache_alloc
Zeroing on mmu_memory_cache_alloc is unnecessary since: - Smaller areas are pre-allocated with kmem_cache_zalloc. - Page pointed by ->spt is overwritten with prefetch_page and entries in page pointed by ->gfns are initialized before reading. [avi: zeroing pages is unnecessary] Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
