The e1000 driver calls memory_region_add_coalescing but
kvm_coalesce_mmio_region is never called for those regions. The bug
dates back to the introduction of the memory region API; to fix it,
the last patch deletes and re-adds coalesced MMIO ranges when building
the FlatViews. The first two patches are preparatory changes.
Paolo Bonzini (3):
memory: extract flat_range_coalesced_io_{del,add}
memory: avoid unnecessary coalesced_io_del operations
memory: update coalesced_range on transaction_commit
