Hm, ppc might need a bit more...
I can't speak for `real machines,' but on my wierd embedded board, pci_alloc_consistent allocates from a special area of memory (not located at 0) that is the only shared memory between PCI devices and the CPU. pci_alloc_consistent happens to fit this situation quite well, but I don't think a bitmask is enough to express the situation.
