Subjectlinux-next: manual merge of the s390 tree with Linus' tree
Hi all,

Today's linux-next merge of the s390 tree got a conflict in:

arch/s390/include/asm/mmu_context.h

between commit:

0b89ede62963 ("s390/mm: fork vs. 5 level page tabel")

from Linus' tree and commit:

f1c1174fa099 ("s390/mm: use new mm defines instead of magic values")

from the s390 tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
