[POWERPC] Remove DISCONTIGMEM cruft from page.h
This looks like cruft to me, these functions don't exist AFAICT, and I can't see that it's possible to even enable DISCONTIGMEM on powerpc anymore. CC'ing some folks who might know better, based on the who-touched-it-last principle. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
