sparc32: fix PAGE_SIZE definition
Use _AC() in definition of PAGE_SIZE so the same definition can be used in C and assembler. Also use PAGE_SIZE in definition of THREAD_SIZE. This commit kill the following comment: "I have my suspicions... -DaveM" I did not find any clue what this referred to anyway. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
