KVM: Fix gfn_to_page() acquiring mmap_sem twice KVM's nopage handler calls gfn_to_page() which acquires the mmap_sem when calling out to get_user_pages(). nopage handlers are already invoked with the mmap_sem held though. Introduce a __gfn_to_page() for use by the nopage handler which requires the lock to already be held. This was noticed by tglx.
