Currently the bitmap_onto() is available only for CONFIG_NUMA=y case,
while some users may benefit out of it and being independent to NUMA
code.

Make it available to users by moving out of ifdeffery and exporting for
modules.  

Wondering if you are trying to have something like

Yes, it looks like.
Can you confirm that your bitmap_scatter() do the same operations as the
existing bitmap_onto() ?

If so, your bitmap_gather() will match my bitmap_off() (patch 4 in this series).

Thanks,
Hervé
