Subject: Optimize the ordering of sections in RW_DATA_SECTION.
X-Git-Tag: v2.6.32-rc1~44
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1b2086227cd1a24f748398c22ea9652c383499cf;p=pandora-kernel.git

Optimize the ordering of sections in RW_DATA_SECTION.

The old RW_DATA_SECTION had INIT_TASK_DATA (which was
more-than-PAGE_SIZE-aligned), followed by a bunch of small alignment
stuff, followed by more PAGE_SIZE-aligned stuff, so you wasted memory
in the middle of .data re-aligning back up to PAGE_SIZE.

This patch sorts the sections by alignment requirements, which should
pack them essentially optimally.
