| * fls64 - find last set bit in a 64-bit word |
| * This is defined in a similar way as the libc and compiler builtin |
| * ffsll, but returns the position of the most significant set bit. |
| * fls64(value) returns 0 if value is 0 or the position of the last |
| * set bit if value is nonzero. The last (most significant) bit is |
