Subject: [PATCH 3/3] xtensa: use new macros for .data.init_task.
Date: Thu, 30 Apr 2009 20:00:27 -0400 [thread overview]
Message-ID: <1241136027-10244-4-git-send-email-tabbott@mit.edu> (raw)
In-Reply-To: <1241136027-10244-3-git-send-email-tabbott@mit.edu>
.data.init_task should not need a separate output section; this change
moves it into the .data section. Also replace aligment of 8192 with
THREAD_SIZE (=8192).
