From c41c5cd3b20a2d81c30498f13b1527847a8fdf69 Mon Sep 17 00:00:00 2001 From: Don Zickus Date: Tue, 26 Sep 2006 10:52:27 +0200 Subject: [PATCH] x86: x86 clean up nmi panic messages Clean up some of the output messages on the nmi error paths to make more sense when they are displayed. This is mainly a cosmetic fix and shouldn't impact any normal code path.
