Subject: [PATCH 6d/10] lguest: the Makefiles
Date: Fri, 09 Feb 2007 21:58:53 +1100	[thread overview]
Message-ID: <1171018733.2718.64.camel@localhost.localdomain> (raw)
In-Reply-To: <1171018674.2718.63.camel@localhost.localdomain>

Finally, we put in the Makefile, so it will build.

You can see the pain involved in creating the switcher code
(hypervisor.S) ready to be copied into the top of memory.
