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.

+          on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+          Unfortunately, on some chip revisions, this sensor is very inaccurate

+          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

+          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
