[PATCH v2 6/6] m32r: Cleanup linker script using new linker script macros.

From: Tim Abbott
Date: Fri Sep 18 2009 - 16:36:50 EST


This patch is largely a straightforward conversion. One thing to note
is that the new macros use fewer separate output sections than the old
code; this should have no functional impact but is relevant for people
objdumping vmlinux files.

Also note that it moves the .data.init_task output sections inside
_edata.
