```c++
static inline uint64_t TrailingBits(uint64_t v, int num_bits) {
if (ARROW_PREDICT_FALSE(num_bits == 0)) return 0;
if (ARROW_PREDICT_FALSE(num_bits >= 64)) return v;
return ((v >> num_bits) << num_bits) ^ v;
```
1. Would you mind change to the code above and I'll rerun a benchmark?
2. Maybe I should wait for Yibo's idea on ARM machine
