Radim Krčmář ca3f087472 KVM: use slowpath for cross page cached accesses ... kvm_write_guest_cached() does not mark all written pages as dirty and code comments in kvm_gfn_to_hva_cache_init() talk about NULL memslot with cross page accesses. Fix all the easy way. The check is '<= 1' to have the same result for 'len = 0' cache anywhere in the page. (nr_pages_needed is 0 on page boundary.) Fixes: 8f964525a1 ("KVM: Allow cross page reads and writes from cached translations.")
