From: Ross Biro Date: Sun, 1 Oct 2006 06:27:25 +0000 (-0700) Subject: [PATCH] allow /proc/config.gz to be built as a module X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f2443ab6c485701576e9116ee44817e66adafd5a;p=openwrt%2Fstaging%2Fblogic.git [PATCH] allow /proc/config.gz to be built as a module The driver for /proc/config.gz consumes rather a lot of memory and it is in fact possible to build it as a module. In some ways this is a bit risky, because the .config which is used for compiling kernel/configs.c isn't necessarily the same as the .config which was used to build vmlinux. But OTOH the potential memory savings are decent, and it'd be fairly dumb to build your configs.o with a different .config.
