- Improve runq_findbit_from() which is used by ULE's circular queue. Mask
of the bits we want to ignore on the first pass rather than doing a
linear scan. This puts us within a few instructions of the cost of
runq_findbit() and removes this function from the top of profiling output
for context switch heavy workloads.
