This patch series cleans up the section names on the sh architecture. It requires the architecture-independent macro definitions from this patch series:
<http://www.spinics.net/lists/mips/msg33499.html>
The long-term goal here is to add support for building the kernel with -ffunction-sections -fdata-sections. This requires renaming all the magic section names in the kernel of the form .text.foo, .data.foo, .bss.foo, and .rodata.foo to not have collisions with sections generated for code like:
static int nosave = 0; /* -fdata-sections places in .data.nosave */ static void head(); /* -ffunction-sections places in .text.head */
Note that these patches have not been boot-tested (aside from testing the analogous changes on x86), since I don't have access to the appropriate hardware.

Tim Abbott (7): sh: Use macros for .bss.page_aligned section. sh: Use macros for .data.page_aligned section. sh: use NOSAVE_DATA macro for .data.nosave section. sh: use new macro for .data.cacheline_aligned section. sh: use new macros for .data.init_task. sh: use new macro for .data.read_mostly section. sh: convert to new generic read_mostly support.
