Subject: [PATCH 00/13] Linker script cleanup patches for various architectures

Hi Linus,

This patch series contains patches cleaning up the linker scripts on
several architectures architectures (as well as one improvement to the
architecture-independent macros).  Everything here has been acked or
reviewed by Sam Ravnborg.  Please merge.

This cross-architecture linker script cleanup project is in
preparation for adding support for building the kernel with
-ffunction-sections -fdata-sections, which is a prerequisite for
Ksplice.

	-Tim Abbott
