- * __ffs - find first bit in word. returns 0 to "BITS_PER_LONG-1".
- * @word: The word to search
- *
- * __ffs() return is undefined if no bit is set.
- *
- * 32-bit fast __ffs by LaMont Jones "lamont At hp com".
- * 64-bit enhancement by Grant Grundler "grundler At parisc-linux org".
- * (with help from willy/jejb to get the semantics right)
- *
- * This algorithm avoids branches by making use of nullification.
- * One side effect of "extr" instructions is it sets PSW[N] bit.
- * How PSW[N] (nullify next insn) gets set is determined by the 
- * "condition" field (eg "<>" or "TR" below) in the extr* insn.
- * Only the 1st and one of either the 2cd or 3rd insn will get executed.
- * Each set of 3 insn will get executed in 2 cycles on PA8x00 vs 16 or so
- * cycles for each mispredicted branch.
