From fdb4c338c8d1d494e17c3422a3ea2129f6791596 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Tue, 17 Jul 2007 18:37:03 -0700 Subject: paravirt: add an "mm" argument to alloc_pt It's useful to know which mm is allocating a pagetable. Xen uses this to determine whether the pagetable being added to is pinned or not.
