Subject: [PATCH 10/16] make emulate_insn receive a vcpu struct.
Date: Mon, 7 Jan 2008 11:05:31 -0200 [thread overview]
Message-ID: <11997111841603-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11997111801864-git-send-email-gcosta@redhat.com>
emulate_insn() needs to know about current eip, which will be,
in the future, a per-vcpu thing. So in this patch, the function
prototype is modified to receive a vcpu struct
