Subject: [PATCH] x86: x86 clean up nmi panic messages
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c41c5cd3b20a2d81c30498f13b1527847a8fdf69;p=linux-beck.git

[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.
