Haven't read the discussion in full, but saw the function here and my 2 cents
are the following:
 1) if we don't have tests for bitmap_remap() / bitmap_bitremap(), we should;
 2) these functions are used at least in one GPIO driver, so it would be nice
    to not touch them if they are not broken (see 1 above).
