As Rasmus suggested [1], the bit remapping APIs should be local to NUMA.
However, they are being in use outside of that for a while. To make
above happen, introduces simplified APIs that can be used otherwise.

It seems we might have yet another user of the above mentioned APIs.

The last patch has not been tested anyhow (except compilation, so
all testing and comments are welcome).

The idea is to get an immutable tag (via my tree) that can be pulled
by bitmap and GPIO trees on the need (while usually I send PR to
the GPIO subsystem).

I don't understand the bitmap changes very well,

Me neither... Oops (it was a joke :-)

but the resulting
changes to cdev look very nice clearly making that code more readable
and maintainable,

While the above is a joke it took quite a time to get into the logic.
Hence this patch. TBH I'm in doubt, that's why asking for careful testing
and reviews.

so FWIW:
Acked-by: Linus Walleij <redacted>

Thank you!
