Subject: [PATCH 3/11] sh: Move TRA/EXPEVT/INTEVT definitions for reuse.
Date: Sat, 28 Jan 2006 00:51:18 +0200	[thread overview]
Message-ID: <20060127225118.GD30816@linux-sh.org> (raw)
In-Reply-To: <20060127224919.GA30816@linux-sh.org>

Currently entry.S is home to these definitions, so we move them
somewhere more sensible. IPR IRQ handling depends on being to
read from INTEVT.
