Subject: [PATCH 03/13] m32r: Define THREAD_SIZE only once.
Date: Tue, 22 Sep 2009 10:22:17 -0400 [thread overview]
Message-ID: <1253629347-23119-4-git-send-email-tabbott@ksplice.com> (raw)
In-Reply-To: <1253629347-23119-1-git-send-email-tabbott@ksplice.com>
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.
