Description: KVM: x86: SYSENTER emulation is broken
References: https://git.kernel.org/linus/f3747379accba8e95d70cec0eae0582c8c182050
Notes:
 bwh> This revealed another earlier fix, commit 1a18a69b7623 ("KVM: x86
 bwh> emulator: reject SYSENTER in compatibility mode on AMD guests").
 bwh> It wasn't marked for stable but the bug might be exploitable by
 bwh> guest userland to crash the guest system.  I've queued it up for
 bwh> wheezy-security along with this.
