[patch] 2.4.20-pre4 sparc32 fixup

[Tomas Szepe]

Hi,

The patch inlined below gets 2.4.20-pre4 to compile (and boot) on my
testmachine again. Trivial stuff mostly, dunno about the page_to_phys
macro, though -- DaveM, could you have a look at it?

Aurora people united please try booting this on your sparc32 oldtimers
if you find the time.

Tomas
