Subject: [patch 05/20] XEN-paravirt: paravirt: reserve fixmap slot
Date: Fri, 12 Jan 2007 17:45:44 -0800 [thread overview]
Message-ID: <20070113014647.589054873@goop.org> (raw)
In-Reply-To: <20070113014539.408244126@goop.org>
[-- Attachment #1: paravirt-fixmap.patch --]
[-- Type: text/plain, Size: 820 bytes --]
Reserve a new fixmap slot for paravirt backends. Xen uses this for
mapping the hypervisor shared-info page, which doesn't really exist in
the guest address space.
