Hi, Mel

     The patch I had test on arm64. I find the great degradation. I test it by micro-bench.
    The patrly data is as following.  and it is stable.  That stands for the allocate and free time. 
    

What type of allocations is the benchmark doing? In particular, what context
is the microbenchmark allocating from? Lastly, how did you isolate the
patch, did you test two specific commits in mainline or are you comparing
4.10 with 4.11-rcX?
