alpha: cleanup in bitops.h
Remove 2 functions private to the alpha implemetation, in favor of similar functions in <linux/log2.h>. Provide a more efficient version of the fls64 function for pre-ev67 alphas. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
