[PATCH 03/13] m32r: Define THREAD_SIZE only once.

From: Tim Abbott
Date: Tue Sep 22 2009 - 10:23:38 EST


Previously, m32r's asm/thread_info.h defined THREAD_SIZE differently
for assembly and C code; now that PAGE_SIZE is usable from assembly,
these can be combined. Also, m32r's asm/processor.h redefines
THREAD_SIZE to the same value; remove this redundant definition.
