Subject: [patch 06/21] Xen-paravirt: paravirt_ops: allocate a fixmap slot
Date: Thu, 15 Feb 2007 18:24:55 -0800 [thread overview]
Message-ID: <20070216022530.953747358@goop.org> (raw)
In-Reply-To: 20070216022449.739760547@goop.org
[-- Attachment #1: paravirt-fixmap.patch --]
[-- Type: text/plain, Size: 790 bytes --]
Allocate a fixmap slot for use by a paravirt_ops implementation. Xen
uses this to map the hypervisor's shared info page, which doesn't have
a pseudo-physical page number, and therefore can't be mapped
ordinarily.
