linux-next: manual merge of the sparc-next tree with the sparc tree

Hi David,

Today's linux-next merge of the sparc-next tree got a conflict in
arch/sparc/mm/init_64.c between commit 4ca9a23765da ("sparc64: Guard
against flushing openfirmware mappings") from the sparc tree and commit
f6d4fb5cc047 ("sparc64 - add mem to iomem resource") from the
sparc-next tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
