Subject: [PATCH 0/5] kvm: memslots lookup optimization

Series speed-ups GFN to memslot lookup time by:
 * introducing LRU cache, which improves looukup time for
   same slot workload (typically boot time of Windows and Linux guest)
 * switching to binary search for GFN to memslot lookup,
   improving lookup time with large amount of memory slots

Igor Mammedov (5):
  kvm: update_memslots: drop not needed check for the same number of
    pages
  kvm: update_memslots: drop not needed check for the same slot
  kvm: search_memslots: add simple LRU memslot caching
  kvm: change memslot sorting rule from size to GFN
  kvm: optimize GFN to memslot lookup with large slots amount
