[PATCH 5/6] m32r: Move the spi_stack_top and spu_stack_top into .data section.

From: Tim Abbott
Date: Sun Sep 06 2009 - 23:13:24 EST

Since these get squashed into the .data output section by the m32r
linker script, it seems likely that they don't need their own input

I'd like an explicit confirmation from Hirokazu Takata that this is
correct (in particular, that there isn't some hidden reason why there
two structures need to be at the start of the .data output section).

This patch is preparation for cleaning up the m32r architecture to use
the new macros in vmlinux.lds.h; if these sections are indeed not
needed, then we can use the RW_DATA_SECTION macro for m32r and save a
bunch of redundant code.
