Marcelo Tosatti	10589a4699	KVM: MMU: Concurrent guest walkers ... Do not hold kvm->lock mutex across the entire pagefault code, only acquire it in places where it is necessary, such as mmu hash list, active list, rmap and parent pte handling. Allow concurrent guest walkers by switching walk_addr() to use mmap_sem in read-mode. And get rid of the lockless __gfn_to_page.
