[XenPPC] Changeset with 3 files on Friday (I think) has broken Xen on Mambo

[Mark F Mergen <mergen@xxxxxxxxxx>]

From the standpoint of us Lone Rangers
using Mambo (Stuart and me), things are broken again.  Below is the
result of trying to boot (this is an unpatched system, doesn't contain
any of my mods) after applying a single changeset with 3 files that I think
was pushed on Friday.  I pulled it, it built OK, I ran out of time
to test then, and I discarded the email that described the changeset.  I'm
guessing, but I think it may have been the same changeset that was sent
again Saturday with the subject line "[XenPPC] [xenppc-unstable] [XEN][POWERPC]
merge" and affected these files:
 xen/arch/powerpc/boot_of.c   |   39
+++++++++++
 xen/arch/powerpc/memory.c    |  150 ++++++++++++++++---------------------------
 xen/include/asm-powerpc/mm.h |    3 
 3 files changed, 98 insertions(+), 94 deletions(-)

The problem appears to be at the lines
highlighted in red below.  Any help or ideas in fixing this will be
much appreciated.
