[Qemu-devel] [RFC v5 00/86] Memory API

[Avi Kivity <avi@redhat.com>]

New in this version:
  - more mindless conversions; I believe there are no longer any destructive
    operations in the tree (IO_MEM_UNASSIGNED)
  - fix memory map generation bug (patch 13)
  - proper 440FX PAM/SMRAM and PCI holes

Caveats:
- some devices (mostly boards) still grab a global memory region instead of
  inheriting it from their bus.  Seen in the code as #include "exec-memory.h"
- pc RAM initialization is a mess - needs to be refactored; this is because
  memory is set up before the memory controller.
