Subject: [PATCH 4/8] lguest: Makefile
Date: Mon, 12 Feb 2007 14:50:19 +1100 [thread overview]
Message-ID: <1171252219.10409.33.camel@localhost.localdomain> (raw)
In-Reply-To: <1171252113.10409.30.camel@localhost.localdomain>
Finally, we put in the Makefile, so it will build.
Linking the switcher code (hypervisor.S) ready to be copied
into the top of memory is the only non-trivial thing here.
