Merge remote-tracking branch 'mst/tags/for_anthony' into staging
pci, pc, acpi fixes, enhancements
This includes some pretty big changes:
- pci master abort support by Marcel
- pci IRQ API rework by Marcel
- acpi generation support by myself
Everything has gone through several revisions, latest versions have been on
list for a while without any more comments, tested by several
people.
Please pull for 1.7.
