From c7e85c42be68fca743df58a306edd29aa295e155 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 18 Jul 2013 20:47:47 +0900 Subject: [PATCH] kprobes/x86: Remove an incorrect comment about int3 in NMI/MCE Remove a comment about an int3 issue in NMI/MCE, since commit: 3f3c8b8c4b2a ("x86: Add workaround to NMI iret woes") already fixed that. Keeping this incorrect comment can mislead developers. Signed-off-by: Masami Hiramatsu Reviewed-by: Jiri Kosina Cc: H.
