[Qemu-devel] [PATCHv3 00/11] Cleanups to qtest PCI handling

[David Gibson]

This series contains a number of cleanups to the libqos code for
accessing PCI devices, and to tests which use it.

The general aim is to improve the consistency of semantics across
functions, and reduce the amount of intimate knowledge of the libqos
PCI layer needed by tests.

This should make it easier to write PCI tests which will be portable
to different guest machines with different PCI host bridge
arrangements.

This series is on top of my ppc-for-2.8 branch, since it contains
patches enabling the virtio tests on ppc, which would otherwise
conflict with the changes here.

Changes since v2:
  * Fixed build bugs in virtio-9p-test, which I didn't find earlier
    due to not having the right libraries installed
  * Fixed an endian bug I accidentally introduced in ide-test
  * Better handling of invalid BAR tokens

Changes since v1:
  * Split out updates to tco-test into separate patch
  * Split out updates to ide-test into separate patch
  * Neater and more general handling of legacy PIO addresses
  * Removed now-redundant fields from platform specific bus structures
  * Introduced CONFIG_BASE() macro to virtio-pci to remove many
    similar assignments
  * Fixed handling of two guest testcasesin ivshmem
  * Added 64-bit accessors
  * Rebase on ppc-for-2.8 to avoid conflict with Laurent's series in
    the same area
