[PATCH 2/2] arm: multi_v7_defconfig: Enable KSM.

From: Daniel DÃaz
Date: Thu Jun 14 2018 - 18:52:35 EST


As per the documentation, Kernel Samepage Merging (available
since 2.6.32) is a memory-saving de-duplication feature,
enabled by CONFIG_KSM=y and activated via sysfs. More
information can be found here:
https://www.kernel.org/doc/Documentation/vm/ksm.txt

When enabled in the kernel, the default is to not do anything
at all, until it is activated at run-time with:
echo 1 > /sys/kernel/mm/ksm/run
