4.3.0 Temporary System Problem. Try again later (10). t81sm863436wmg.6 - gsmtp
This series simplifies various memory API calls when creating
memory regions.
Most of the patches are generated with Coccinelle semantic
patches (provided).
Few more cleanups added while writting the patches have been
added.
v1 was 'Let devices own the MemoryRegion they create':

Since v1:
- understood a bit more Peter Maydell comments regarding
how memory devices are migrated.
