[PATCH v2 00/38] Memory API, batch 2: PCI devices

[Avi Kivity <avi@redhat.com>]

This is a mostly mindless conversion of all QEMU PCI devices to the memory API.
After this patchset is applied, it is no longer possible to create a PCI device
using the old API.

An immediate benefit is that PCI BARs that overlap each other are now handled
correctly: currently, the sequence

  map BAR 0
  map BAR 1 at an overlapping address
  unmap either BAR 0 or BAR 1

will leave a hole where the overlap exists.  With the patchset, the memory map
is restored correctly.

Note that overlaps of PCI BARs with memory or non-PCI resources are still not
resolved correctly; this will be fixed later on.

The vga patches have ugly intermediate states; however the result is fairly clean.

This patchset should be merged after

  memory: synchronize dirty bitmap before unmapping a range
  memory: use signed arithmetic

though there's no hard dependency.

Changes from v1:
 - cmd646 type fix
 - folded a fixlet into its parent


Avi Kivity (38):
