powerpc: Merge enough to start building in arch/powerpc.
This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.

+
+config TAU_INT
+ bool "Interrupt driven TAU driver (DANGEROUS)"

+ ---help---
+ The TAU supports an interrupt driven mode which causes an interrupt
+ whenever the temperature goes out of range. This is the fastest way
+ to get notified the temp has exceeded a range. With this option off,
+ a timer is used to re-check the temperature periodically.
+
+ However, on some cpus it appears that the TAU interrupt hardware
+ is buggy and can cause a situation which would lead unexplained hard
+ lockups.
+
+ Unless you are extending the TAU driver, or enjoy kernel/hardware
+ debugging, leave this option off.
+
+config TAU_AVERAGE
+ bool "Average high and low temp"
+ depends on TAU
+ ---help---
+ The TAU hardware can compare the temperature to an upper and lower
+ bound. The default behavior is to show both the upper and lower
+ bound in /proc/cpuinfo. If the range is large, the temperature is
+ either changing a lot, or the TAU hardware is broken (likely on some
+ G4's). If the range is small (around 4 degrees), the temperature is
+ relatively stable. If you say Y here, a single temperature value,
+ halfway between the upper and lower bounds, will be reported in
+ /proc/cpuinfo.
+
+ If in doubt, say N here.
