Date: Wed, 22 May 2013 14:07:42 -0700
From: Andy Lutomirski <luto@...capital.net>
To: linux-kernel@...r.kernel.org
Cc: x86@...nel.org, trinity@...r.kernel.org,
Andy Lutomirski <luto@...capital.net>, kvm@...r.kernel.org
Subject: [PATCH 3/5] x86: Annotate _ASM_EXTABLE users to distinguish uaccess from everything else
The idea is that the kernel can be much more careful fixing up
uaccess exceptions -- page faults on user addresses are the only
legitimate reason for a uaccess instruction to fault.
Signed-off-by: Andy Lutomirski <luto@...capital.net>

I'm not 100% sure what's happening in the KVM code. Can someone familiar
with it take a look?
