From 56bec2f9d4d05675cada96772a8a93010f4d82bf Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 31 Mar 2021 11:38:40 +1100 Subject: [PATCH] powerpc/mm/64s: Add _PAGE_KERNEL_ROX In the past we had a fallback definition for _PAGE_KERNEL_ROX, but we removed that in commit d82fd29c5a8c ("powerpc/mm: Distribute platform specific PAGE and PMD flags and definitions") and added definitions for each MMU family. However we missed adding a definition for 64s, which was not really a bug because it's currently not used. But we'd like to use PAGE_KERNEL_ROX in a future patch so add a definition now.
