I'm sorry, but that's _exactly_ the problem.  You are pushing an
SN2-specific hacks into the ia64 kernel and you seem to think that's
OK.  I don't want the ia64 kernel to turn into a collection of
vendor-specific hacks (whether from HP, Intel, SGI, or anyone else).
Yes, doing clean, general and efficient APIs is hard, requires
thinking, talking to others, etc., but it's the only way to get a
kernel that's maintainable.  If you only care about
efi_memmap_walk_uc() for SN2, that's fine by me, but in that case it
will stay in the SN2 tree.  If you want something in the normal ia64
kernel, please propose an API (and patch) that actually makes sense
beyond SN2.
