At least one of the faulty users (wireless) is in generic code and needs
fixing regardless.

For better or worse; the bitmap stuff is defined to work on unsigned
long. Using it on smaller types already relies on small endian; but
further enabling just makes it worse I feel. Better have the rules be
uniform.
