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

The macros don't do type checking so it will work for both 32-bit and 64-bit.
