KVM: MMU: Avoid calling gfn_to_page() in mmu_set_spte()
Since gfn_to_page() is a sleeping function, and we want to make the core mmu spinlocked, we need to pass the page from the walker context (which can sleep) to the shadow context (which cannot). [marcelo: avoid recursive locking of mmap_sem] Signed-off-by: Avi Kivity <avi@qumranet.com>
