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.

MFC r257161, r257169, r257178, r257190, r257191
Add pmap_mapdev_attr() and pmap_kenter_attr() interfaces.
Fix concurrency issues with TLB1 updates and make pmap_kextract() search TLB1 mappings as well
Interrelated improvements to early boot mappings: - Remove explicit requirement that the SOC registers be found except as an optimization (although the MPC85XX LAW drivers still require they be found externally, which should change). - Remove magic CCSRBAR_VA value. - Allow bus_machdep.c's early-boot code to handle non 1:1 mappings and systems not in real-mode or global 1:1 maps in early boot. - Allow pmap_mapdev() on Book-E to reissue previous addresses if the area is already mapped. Additionally have it check all mappings, not just the CCSR area.
Add some extra sanity checking and checks to printf format specifiers.
Bump initial TLB size. The kernel is not necessarily less than 16 MB
Handle (in a slightly ugly way) ePAPR-type loaders that just place a device tree into r3.

Unbreak non-SMP builds. This was broken by r259284. Also, reorganize the code introduced in that revision a bit.

MFC r257991, r257992, 257993, 258504
r257991: Consolidate Apple firmware hacks and improve them by switching on the presence of mac-io devices in the tree, which uniquely identifies Apple hardware.
r257992: Allow OF_decode_addr() to also be able to map resources on big-endian devices. To this end, make PCI device detection rely on the device_type field rather than name, as per the standard.
r257993:
Make tsec work with the device tree present on the RB800. The previous code assumed that the MDIO bus was a direct child of the Ethernet interface. It may not be and indeed on many device trees is not. While here, add proper locking for MII transactions, which may be on a bus shared by several MACs.
r258504:
Save and restore the trap vectors when doing OF calls on pSeries machines.
It turned out that on pSeries machines the call into OF modified the trap vectors and this made further behaviour unpredictable.
With this commit I'm now able to boot multi user on a network booted environment on my IntelliStation 285. This is a POWER5+ machine.
