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
