Hi,
Below is a patch to fix a couple of issues with fake numa node creation
on ppc:
1) Presently, fake nodes could be created such that real numa node
boundaries are not respected. So a node could have lmbs that belong to
different real nodes.
2) The cpu association is broken. On a JS22 blade fo

Switch to using the Power ISA defined PTE format when we have a 64-bit
PTE. This makes the code handling between fsl-booke and book3e-64
similiar for TLB faults.
Additionally this lets use take advantage of the page size encodings and
full permissions that the HW PTE defines.

Add defines for the other page sizes. Even if HW doesn't support them
we made them use them for hugetlbfs support.

A misconfiguration by the firmware of the U4 PCIe bridge on PowerMac G5
with the U4 bridge (latest generations, may also affect the iMac G5
"iSight") is causing us to re-assign the PCI BARs of the video card,
which can get it out of sync with the firmware, thus breaking offb.
This works around it
