Subject: [PATCH v2 3/6] m32r: Move GET_THREAD_INFO definition out of asm/thread_info.h.
Date: Fri, 18 Sep 2009 16:32:46 -0400 [thread overview]
Message-ID: <1253305969-6948-4-git-send-email-tabbott@ksplice.com> (raw)
In-Reply-To: <1253305969-6948-1-git-send-email-tabbott@ksplice.com>
Previously, asm/thread_info.h was not usable from linker scripts
because it contains a piece of .macro code. Since that code was only
used in the m32r entry.S, the right fix is probably to move the macro
there.
