Subject: [PATCH 0/6] section name cleanup for arm

This patch series cleans up the section names on the arm
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 (6):
  arm: use _AC(1, UL) when defining PAGE_SIZE.
  arm: convert to use __HEAD and HEAD_TEXT macros.
  arm: use NOSAVE_DATA macro for .data.nosave section.
  arm: use new macro for .data.cacheline_aligned section.
  arm: use new macros for .data.init_task.
  arm: use PERCPU macro in linker script.
