Subject: [PATCH 4/4] build system: section garbage collection for vmlinux
Date: Tuesday, September 11, 2007 - 4:22 pm

This is the core patch of the series.

It adds CONFIG_DISCARD_UNUSED_SECTIONS,
adds KEEP() directives to linker scripts,
adds custom module linker script which is needed
to avoid having modules with many small sections.
Modules got a bit smaller too, as a result.

This patch is slighty more risky than first three,
probably need to go into -mm first.
It should be safe with CONFIG_DISCARD_UNUSED_SECTIONS off, though.
