Of course you *can*, but do you (or anyone else) actually does this?
AFAIK this is not a very common business model.

Just intended to post the patch... :-)
- sync up with new pte/pfn/page/tlb macros
- pcibios_init() should return int;
- find last bit set: ctlz for ev67 and above, generic for others.

I'm not sure what to do with this. I doubt that we ever want this
file on alpha. For myself I moved "#include <asm/suspend.h>"
under #ifdef CONFIG_SOFTWARE_SUSPEND and everything compiles.

If you're not capable of reading the list archives, and picking up the
patches which I believe I recall seeing, then no - I suspect you are indeed
beyond help.
