Does that mean that are there filesystems that are passing pointers to
the find_bit functions which are _not_ aligned to an "unsigned long" ?

If there are, we should _not_ convert 32-bit ARM to use word loads or
use the generic code; unaligned loads are expensive on older ARM CPUs,
at least not the code for older ARM CPUs.
