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.

Avi Kivity	edf884172e	KVM: Move arch dependent files to new directory arch/x86/kvm/ ... This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: Avi Kivity <avi@qumranet.com>	2008-01-30 18:01:18 +02:00
