bitops for handling 32 bits

[Kevin Wilson]

Hi all,
Is there a kernel API for handling 32 bits ?
I see a macro like BIT(nr)
http://lxr.free-electrons.com/source/include/linux/bitops.h#L6

#define BIT(nr)                 (1UL << (nr))

and also
#define BIT_ULL(nr)             (1ULL << (nr))

However, these macros are using 64 bit semantics, so if I will use
them with 32 bits values
the results will  be wrong.

Any ideas ?

Regards,
Kevin
