How so? Of course I could write an generic set_bit32, but the question is if these bit operations would be still atomic on SMP and not conflict with fields occuping the same 8 byte slot. I remember you flaming someone some time ago because he used set_bit in an atomic fashion on a type smaller than unsigned long for example.
It's OK if you align the pointer to 8 bytes, and subsequently the bit offset as appropriate. :-)
