From e0a3647fd7729bee1ed9667ce5d8eb88f0604138 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 1 Aug 2007 16:55:07 +0900 Subject: [PATCH] sh: Fix SH-X3 FPU exception handling. SH-X3 has the FPU exceptions on different vectors completely, patch in do_fpu_state_restore() to the proper vectors. Results in a much happier userspace.
