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

This patchset introduces cpuidle infrastructure to POWER, prototyping

will *not* build on x86/other POWER platforms.

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.
