[PATCH 0/6] section name cleanup for arm

From: Tim Abbott
Date: Thu Apr 30 2009 - 19:44:55 EST


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: 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.
