* [S390] bitops: remove likely annotationsHeiko Carstens2009-03-261-6/+6
| | | | | | | | | likely/unlikely profiling revealed that none of the branches in bitops is taken likely or unlikely. So remove the annotations. In addition the generated code is shorter.

* [S390] fix ext2_find_next_bitEric Sandeen2008-08-211-3/+3
| | | | | | | | | | | | | | | ext4 does not work on s390 because ext2_find_next_bit is broken. Fortunately this function is only used by ext4. The function uses ffs which does not work analog to ffz. The result of ffs has an offset of 1 which is not taken into account. To fix this use the low level __ffs_word function directly instead of the ill defined ffs. In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit by passing the bit offset into __ffz_word instead of adding it after the function call returned.
