SubjectRe: [parisc-linux] Untested port of parisc_device to generic device interface

I'd like to know more about what these machines look
like in the real world. Specifically, I am interested in the
trade-off of having a parameter to wback_fake_consistent
so that it could be enabled or disabled on an individual basis.

I suspect that the parameter is not worth the clutter because
these "partially consistent" machines either have a large amount of
consistent memory, so the case of the allocation failing in the is not
worth supporting, or it is easy to check for consistent memory on them
with something like "if ((unsigned long) vaddr < 0xwhatever)", but I'm
just guessing.
