Subject: [PATCH] ARC, thp: remove infrastructure for handling splitting PMDs
Date: Fri, 12 Feb 2016 16:11:01 +0530 [thread overview]
Message-ID: <1455273661-1918-1-git-send-email-vgupta@synopsys.com> (raw)
With THP refcounting work, no need to mark PMDs splitting.
(ARC got missed under the sweeping arch change as THP support was likely
not present in orig baseline)
