Heiko Carstens b1cb7e2b6c s390/bitops: use flogr instruction to implement __ffs, ffs, __fls, fls and fls64 ... Since z9 109 we have the flogr instruction which can be used to implement optimized versions of __ffs, ffs, __fls, fls and fls64. So implement and use them, instead of the generic variants. This reduces the size of the kernel image (defconfig, -march=z9-109) by 19,648 bytes.
