* fls: change parameter to unsigned intMatthew Wilcox2019-01-041-1/+1
| | | | | | | | | | | | | | | | | | When testing in userspace, UBSAN pointed out that shifting into the sign bit is undefined behaviour. It doesn't really make sense to ask for the highest set bit of a negative value, so just turn the argument type into an unsigned int. Some architectures (eg ppc) already had it declared as an unsigned int, so I don't expect too many problems.

* arch,c6x: Convert smp_mb__*()Peter Zijlstra2014-04-181-7/+1
| | | | | | | | | | | | | | | | | c6x doesn't have a barrier.h and completely relies on asm-generic/barrier.h. Therefore its smp_mb() is barrier() and we can use the default versions that are smp_mb().
