Subject: [PATCH 4/7] powerpc: Enable KSM on pseries and ppc64 defconfigs
Date: Tue, 20 Jan 2015 10:24:22 +1100 [thread overview]
Message-ID: <1421709865-6368-4-git-send-email-anton@samba.org> (raw)
In-Reply-To: <1421709865-6368-1-git-send-email-anton@samba.org>
KSM will only be used on areas marked for merging via madvise, and it
is showing nice improvements on KVM workloads, so enable it by
default.
