These macros will be used in providing support for generating 128 bit masks. The macros wouldn't work in all assembler flavors for reasons described in the comments on top of declarations. Enforce it for more by adding !__ASSEMBLY__ guard.

Compared to what is already in include/linux/bits.h, the definitions need to use the uglified versions of UL(), ULL(), BITS_PER_LONG and BITS_PER_LONG_LONG (which did not even exist), but otherwise expand to the same content.
