x86/paging: make log-dirty operations preemptible
Both the freeing and the inspection of the bitmap get done in (nested)
loops which - besides having a rather high iteration count in general,
albeit that would be covered by XSA-77 - have the number of non-trivial
iterations they need to perform (indirectly) controllable by both the
guest they are for and any domain controlling the guest (including the
one running qemu for it).
This is CVE-2014-5146 / XSA-97.
