From: Jo-Philipp Wich Date: Sat, 13 Jan 2018 13:46:11 +0000 (+0100) Subject: target: disable CONFIG_PROC_PAGE_MONITOR on most targets X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7e99a6ba690f27b36e99144178c71f0687b07ad9;p=openwrt%2Fstaging%2Fblogic.git target: disable CONFIG_PROC_PAGE_MONITOR on most targets Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled for virtual targets such as malta or potent ones like x86. This saves up to 4KB of uncompressed kernel size and significantly decreases CPU load under certain workloads.
