Subject: [PATCH] migration/ram: Fix calculation of gfn correpond to a page in
ramblock
A RAMBlock contains a host memory region which may consist of many
discontiguous MemoryRegion in AddressSpace of a Guest, so we cannot
get gpa by MemoryRegion.addr. Since KVM memslot records the relationship
between gpa and hva, so we can pass the hva of page in RAMBlock to
kvm_phisical_memory_addr_from_host() to get the expected gpa.
