Each of these drivers has a copy of the same trivial helper function to
convert the pointer argument and then call the native ioctl handler.

We now have a generic implementation of that, so use it.

Arnd, would you consider including a patch as part of/after this
series to make compat_ioctl in drivers/infiniband/core/uverbs_main.c
use this as well?  Looks like a bug too?

That should be included in patch 5 in this series. I may have skipped
some Cc there since it had too many recipients (sent only to the
mailing lists instead).
