I am really pleased to see the 30%+ improvement on unixbench on single core.

Hi barry.
I do some test on Kunpeng arm64 machine use Unixbench.
The test result as below.
One core, we can see the performance improvement above +30%.
./Run -c 1 -i 1 shell1
w/o
System Benchmarks Partial Index BASELINE RESULT INDEX
Shell Scripts (1 concurrent)
Though ARM64 has the hardware to do tlb shootdown, the hardware
broadcasting is not free.
A simplest micro benchmark shows even on snapdragon 888 with only
8 cores, the overhead for ptep_clear_flush is huge even for paging
out one page mapped by only one process:
5.36% a.out[kernel.kallsyms]
