From bd40e8132336fbc3f2857f24720e11b6c1c9ac26 Mon Sep 17 00:00:00 2001 From: Aoi Shinkai Date: Wed, 10 Dec 2008 13:30:28 +0900 Subject: sh: Delete unnecessary mov in the interrupt exception entry point. The INTEVT read at interrupt exception entry is uneccessary, as the read is deferred until we are ready to enter do_IRQ(). The kgdb nmi path still requires it, so move it there.
