linux/bits.h: Extract common header for vDSO The vDSO library should only include the necessary headers required for a userspace library (UAPI and a minimal set of kernel headers). To make this possible it is necessary to isolate from the kernel headers the common parts that are strictly necessary to build the library. Split bits.h into linux and common headers to make the latter suitable for inclusion in the vDSO library.

vdso/bits.h: Add BIT_ULL() for the sake of consistency The minimization done in 3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO") was required to isolate the VDSO build from the larger kernel header impact. The split added some inconsistency since BIT() and BIT_ULL() are now defined in the different files which confuses unprepared reader. Move BIT_ULL() to vdso/bits.h. No functional change.
