Subject: [PATCH 2/2] 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.
