The phys_ram_dirty array consists of 8-bit values for storing 3 dirty bits.
Change to more generic phys_ram_flags and use lower 4-bits for dirty status and
leave upper 4 for other uses of marking memory pages.
One potential use for upper bits is to mark certain device pages to not be
migrated.
So
Non-migrated memory is useful for devices that do not want to take memory
region data with them on migration.
As suggested by Avi, an alternative approach could add a "flags" parameter to
cpu_register_physical_memory() rather than explicityly call
cpu_mark_pages_no_migrate(). However, having a se

Rearrange code so that in the end, mc146818 can be compiled once.
The other patches should be safe, but I'm not so sure about coalesced

Also, is the periodic timer optimization (removed in 1/4) very important?
