Boot tests are still going on, but:

powerpc:defconfig (and others):

arch/powerpc/include/asm/book3s/64/pgtable.h: In function 'pte_modify':
arch/powerpc/include/asm/book3s/64/pgtable.h:74:24: error: '_PAGE_DEVMAP' undeclared

Introduced by commit 4091b46b1dfe ("mm: Preserve _PAGE_DEVMAP across mprotect() calls")
which fixes ebd31197931d for ppc64 which is not in v4.9.y. Unfortunately it also fixes
69660fd797c3 ("x86, mm: introduce _PAGE_DEVMAP") which _is_ in the branch. ebd31197931d
doesn't apply cleanly, so either someone needs to backport it, or the ppc changes need
to be dropped from 4091b46b1dfe.


Excellent example why it isn't a good idea to fix two commits with one.
