BIT is unsigned long, which is 32-bit on ARCH=arm, hence the overflow warning. Switch to BIT_ULL, which is 64-bit and will not overflow.

This code never runs on 32-bit platforms, so another option would be to not try and build this on 32-bit configurations either. But none of the rest of the code is built conditionally, so fixing this is preferable.
Applied, thanks.
