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.
