on rc3 we get:
https://raw.githubusercontent.com/hisilicon/kernel-dev/private-topic-sas-5.19-faddr2line-linux-rc3/before2
With dcea997beed6 reverted on rc3:
https://raw.githubusercontent.com/hisilicon/kernel-dev/private-topic-sas-5.19-faddr2line-linux-rc3/after2
This is my branch is you want to see what I have: https://github.com/hisilicon/kernel-dev/commits/private-topic-sas-5.19-faddr2line-linux-rc3
