Paul Mackerras daec962e27 powerpc: Use arch/powerpc/mm and arch/powerpc/lib for 64-bit 
This also puts a copy of indirect_pci.c in arch/powerpc/sysdev
so that we don't need to build in arch/ppc/syslib.

Paul Mackerras c0c0d996d0 powerpc: Get merged kernel to compile and run on 32-bit SMP powermac. 
This updates the powermac SMP code to use the mpic driver instead of
the openpic driver and fixes the SMP-dependent context switch code.
We had a subtle bug where we were using interrupt numbers 256-259 for
IPIs, but ppc32 had NR_IRQS = 256.  Moved the IPIs down to use interrupt
numbers 252-255 instead.

Paul Mackerras 14cf11af6c 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.
