From 9a032e393a8bc888a9b0c898cbdb9db2cee7b536 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Wed, 17 Oct 2012 13:37:49 -0700 Subject: xen: add pages parameter to xen_remap_domain_mfn_range Also introduce xen_unmap_domain_mfn_range. These are the parts of Mukesh's "xen/pvh: Implement MMU changes for PVH" which are also needed as a baseline for ARM privcmd support.

For Xen on ARM a PFN is 64 bits so we need to use the appropriate type here.
