OK. Found it... Here...
467 /*
468 * fls: find last bit set.
469 */
470
471 #define fls(x) generic_fls(x)

I took it out. I guess it's not needed anymore because of this:

318 /*
319 * fls: find last bit set.
320 */
321 #if defined(__alpha_cix__) && defined(__alpha_fix__)
322 static inline int fls(int word)
323 {
324 long result;
325 __asm__("ctlz %1,%0" : "=r"(result) : "r"(word &
0xffffffff));
326 return 64 - result;
327 }
328 #else
329 #define fls generic_fls
330 #endif

Right? :o)

Greetz,
