+Subject: [PATCH] mm: Preserve _PAGE_DEVMAP across mprotect() calls
+References: bsc#1111028
+Patch-mainline: Not yet, submitted 09 Oct 2018
+
+Currently _PAGE_DEVMAP bit is not preserved in mprotect(2) calls. As a
+result we will see warnings such as:

+
+when mprotect(2) gets used on DAX mappings. Also there is a wide variety
+of other failures that can result from the missing _PAGE_DEVMAP flag
+when the area gets used by get_user_pages() later.
+
+Fix the problem by including _PAGE_DEVMAP in a set of flags that get
+preserved by mprotect(2).

+Fixes: ebd31197931d ("powerpc/mm: Add devmap support for ppc64")
