From 66f7de8634b39fb685556419fc12522e96990d32 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 22 Jun 2010 17:52:47 +0200 Subject: [PATCH] microblaze: entry.S: Macro optimization We are not working with values from MSR that's why we can discard it and use r11 for different purpose without saving/restoring.
