- * _Bitfield_Find_first_bit
- *
- * DESCRIPTION:
- *
- * This routine returns the bit_number of the first bit set
- * in the specified value. The correspondence between bit_number
- * and actual bit position is processor dependent. The search for
- * the first bit set may run from most to least significant bit
- * or vice-versa.
- *
- * NOTE:
- *
- * This routine is used when the executing thread is removed
- * from the ready state and, as a result, its performance has a
- * significant impact on the performance of the executive as a whole.
