stable/3.18.y builds cleanly these days, so most warnings are all regressions in -rt, possibly not the KM_TYPE_NR warning, which seems to be an actual bug in stable kernels.

We should backport adec640e0366 ("mlx5: stop including <asm-generic/kmap_types.h>")
In stable/linux-3.18.y, this is also wrong, but no warning shows up, since we don't include the right header there, only the wrong one. It's probably harmless, but I'm not completely sure about htis one.
Greg, maybe you can just add this to 3.18.y?

I'm guessing that the same problems exist in the other stable-rt kernels, so we probably need to fix them on all branches.

Ok, now queued up, thanks.

Arnd,
Thanks for Ccing us. I'll have a look. Some of these small issues probably should be fixed in upstream RT as well. I'll see if the #if not #ifdef is in the RT development branch, as I usually just do straight pulls from that.
