From 2d19fc639516dc7b4184450b315c931d38549e61 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Wed, 27 Jan 2016 12:04:20 +0530 Subject: powerpc/mm: Fixup _HPAGE_CHG_MASK This was wrongly updated by commit 7aa9a23c69ea ("powerpc, thp: remove infrastructure for handling splitting PMDs") during the last merge window. Fix it up. This could lead to incorrect behaviour in THP and/or mprotect(), at a minimum.
