Subject: [patch 03/21] Xen-paravirt: Add pagetable accessors to pack and unpack pagetable entries
Date: Thu, 15 Feb 2007 18:24:52 -0800	[thread overview]
Message-ID: <20070216022530.657670466@goop.org> (raw)
In-Reply-To: <20070216022449.739760547@goop.org>

[-- Attachment #1: paravirt-pte-accessors.patch --]
[-- Type: text/plain, Size: 13842 bytes --]

Add a set of accessors to pack, unpack and modify page table entries
(at all levels).  This allows a paravirt implementation to control the
contents of pgd/pmd/pte entries.  For example, Xen uses this to
convert the (pseudo-)physical address into a machine address when
populating a pagetable entry, and converting back to pphys address
when an entry is read.
