Subject: [RESEND PATCH v3 3/6] bitmap: Make bitmap_onto() available to users

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.
