Most of these should be fixed with 3.19.52, which is warning free now, but at
least two of them are regressions introduced by -rt.

Will be fixed in 3.18.53.

It seems that 3.18.y still needs a backport of
adec640e0366 ("mlx5: stop including <asm-generic/kmap_types.h>")
For some reason this didn't show up with the other build tests without the
-rt patchset.

I think these are all fixed in 3.18.52.

This one is queued for 3.18.53.
