Thanks for your review.
I will disable the instrumentation of arch/arm/kvm/hyp in the next version. 
Just like this:

You need to extend this at least to arch/arm/kvm/hyp/Makefile, as the
KASAN shadow region won't be mapped in HYP. See commit a6cdf1c08cbfe for
more details (all the arm64 comments in this patch apply to 32bit as well).

Thanks,

Disable instrumentation for arch/arm/boot/compressed/*
and arch/arm/vdso/* because those code won't linkd with
kernel image.

Disable kasan check in the function unwind_pop_register
because it doesn't matter that kasan checks failed when
unwind_pop_register read stack memory of task.
