I have successfully applied your patches on my arm64 linux. And I could
start it with a qemu machine(virt). However, I don't know the way to test
the performance it brings to the kernel. Do you have some suggestions?


Kernel text replication performance test results depend on your workload. Different workloads will behave differently.And performance testing in a virtual machine is not very accurate.


Thanks,
