* _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.
