Subject: [PATCH 0/8] section name cleanup for powerpc
Date: Thu, 30 Apr 2009 19:56:09 -0400 [thread overview]
Message-ID: <1241135777-9462-1-git-send-email-tabbott@mit.edu> (raw)
This patch series cleans up the section names on the powerpc
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 (8):
powerpc: Remove unused __page_aligned macro.
powerpc: share .data output section definition between 32 and 64
bits.
powerpc: Use macros for .data.page_aligned section.
powerpc: use NOSAVE_DATA macro for .data.nosave section.
powerpc: use new macro for .data.cacheline_aligned section.
powerpc: use new macros for .data.init_task.
powerpc: use new macro for .data.read_mostly section.
powerpc: convert to new generic read_mostly support.
