More header cleanups, strip out typedefs and remove cruft. There are a lot of magic macros that can go and also a great deal of abuse of volatile that is not needed any more as this patch set cleans up the misuse of pointer access to ISA and PCI space. It now builds cleanly on 64bit, although there is more work left to do Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
