The grow() function in the rheap library allocates a larger array of blocks,
copies the contents of the old blocks array to the newly allocated array and
fixes the list_head pointers after the copy. At the end, the new blocks must
be enqueued to the empty_list of the rh_info_t structure. This patch fixes
a bug where the code was indexing past the end of the array when enqueueing
blocks. The UCC ethernet driver, which uses the rheap allocator, experiences
kernel panics because of this bug.

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree. I think this accomplises
everything wanted, though there might be a few references I missed.

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.
