I agree. The current stuff seems to be working enough for basic
functionality (read: getting the distro installer to work). If the only
problem we have is with SR-IOV or hotplug I can deal with that.
The right solution is to once and for all consider IO and MEM as two
completely separate address spaces that require completely different
passes IMHO.
Cheers,
Ben.
