kvm: search_memslots: add simple LRU memslot caching In typical guest boot workload only 2-3 memslots are used extensively, and at that it's mostly the same memslot lookup operation. Adding LRU cache improves average lookup time from 46 to 28 cycles (~40%) for this workload. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
