[PATCH 0/2] kvm: clear dirty bitmaps from all overlapping memslots

[Paolo Bonzini]

A single ram_addr (representing a host-virtual address) could be aliased
to multiple guest physical addresses.  Since the KVM dirty page reporting
works on guest physical addresses, we need to clear all of the aliases
when a page is migrated, or there is a risk of losing writes to the
aliases that were not cleared.
