KVM: MMU: Simplify page table walker

Browse source

Simplify the walker level loop not to carry so much information from one
loop to the next.  In addition to being complex, this made kmap_atomic()
critical sections difficult to manage.

As a result of this change, kmap_atomic() sections are limited to actually
touching the guest pte, which allows the other functions called from the
walker to do sleepy operations.  This will happen when we enable swapping.
