Regarding the nomenclature, I created the term "clump" to represent an
8-bit value that was not necessarily a byte yet was a contiguous
grouping of bits. With this patchset, we now have a more generic
for_each_set_clump macro that can handle values larger and smaller than
8-bits.

Would it make sense to retire the term "clump" and instead use "nbits"
where applicable, in order to match the existing convention used by the
bitmap functions; for instance, would it be better to name this macro
for_each_set_nbits?
