[Qemu-devel] [PATCH 0/6] ioport related clean ups

[Isaku Yamahata]

This patch series cleans up io port emulation
sliming down bloated vl.c a bit and consolidated
ones used for user emulation.

Changes from v1:
- removed unintended stderr.
- use uint{32, 16, 8}_t instead of uint32_t.

Isaku Yamahata (6):
  split out ioport related stuffs from vl.c into ioport.c.
  use constant IOPORTS_MASK instead of 0xffff.
  ioport: consolidate duplicated logic in register_ioport_{read,
    write}().
  ioport: remove some #ifdef DEBUG_UNUSED_IOPORT.
  consolidate user cpu_{in, out}[bwl] into ioport-user.c
  use uint{32, 16, 8}_t for ioport port and value instead of int.
