[Qemu-devel] [PATCH 0/3] Memory API mutators

[Avi Kivity]

This patchset introduces memory_region_set_enabled() and
memory_region_set_address() to avoid the requirement on memory
routers to track the internal state of the memory API (so they know
whether they need to add or remove a region).  Instead, they can
simply copy the state of the region from the guest-exposed register
to the memory core, via the new mutator functions.

Please review.  Do we need a memory_region_set_size() as well?  Do we want

  memory_region_set_attributes(mr,
                               MR_ATTR_ENABLED | MR_ATTR_SIZE,
                               (MemoryRegionAttributes) {
                                   .enabled = s->enabled,
                                   .address = s->addr,
                               });

?
