linux-next: manual merge of the powerpc tree with Linus' tree

arch/powerpc/kernel/prom.c

between commits:

beff82374b25 ("powerpc: Update cpu_user_features2 in scan_features()")
4705e02498d6 ("powerpc: Update TM user feature bits in scan_features()")

from Linus' tree and commit:

5ddd6bb5968e ("powerpc/mm/radix: Use firmware feature to enable Radix MMU")

from the powerpc 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.
