Subject[PATCH 4.10 161/167] powerpc/mm: Add MMU_FTR_KERNEL_RO to possible feature mask
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

commit a5ecdad4847897007399d7a14c9109b65ce4c9b7 upstream.

Without this we will always find the feature disabled.
