Do not assume a value for #address-cells when parsing the OF translations map. This allows the kernel to get farther with OpenBIOS on 64-bit CPUs.
Actually look up #address-cells instead of assuming it is correlated with the Uninorth version number.
#interrupt-cells belongs to the iparent, not the device parent.
Add a sysctl to allow disabling resetting the OF syscons.
For PCI<->PCI bridges, #address-cells may be 3.
Make RTAS calls, which call setfault() to recover from machine checks, preserve any existing fault buffer.
badaddr() is used only in the grackle PCI driver, so move its definition there. Clean up a spurious setfault() declaration as well.
This [phyp_console] driver doesn't need the /options node, so don't check for it.
Use the Open Firmware-based CPU frequency determination as a generic fallback if we can't measure CPU frequency. This is also useful on a variety of embedded systems using FDT.

Merge in support for PAPR-compliant (Power Architecture Platform Requirements) systems from the projects/pseries branch. This in principle includes all IBM POWER hardware released in the last 15 years with the exception of POWER3-based systems when run in 64-bit mode. The main development target, however, has been the PAPR logical partition support that is the default target in KVM on POWER and QEMU -- mileage may vary on actual hardware at present. Much of the heavy lifting here was done by Andreas Tobler.
