Subject: [patch 03/11] x86: nmi_64.c - move do_nmi(), stop_nmi() and restart_nmi() implementation to traps_64.c
Date: Sat, 24 May 2008 19:36:33 +0400 [thread overview]
Message-ID: <4838373e.1438560a.6987.3a12@mx.google.com> (raw)
In-Reply-To: 20080524153630.669797039@gmail.com
[-- Attachment #1: nmi-64-move-spec-func-to-traps --]
[-- Type: text/plain, Size: 2225 bytes --]
traps_32.c already holds these functions so do the same for traps_64.c
