Subject: [PATCH 1/2] KVM: x86 emulator: Re-add VendorSpecific tag to VMMCALL insn
Date: Tue,  5 Apr 2011 16:28:30 +0300	[thread overview]
Message-ID: <1302010111-23431-2-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1302010111-23431-1-git-send-email-avi@redhat.com>

VMMCALL needs the VendorSpecific tag so that #UD emulation
(called if a guest running on AMD was migrated to an Intel host)
is allowed to process the instruction.
