According to the kernel test robot's report, this may fail due to a dependency
issue.
I will fix it in the next version as:
select KEXEC_PE_IMAGE if DEBUG_INFO_BTF && BPF_SYSCALL
This dependency is introduced in patch [5/12].
Cc Catalin, since I'm making changes to address this issue, I'll drop your ack
in the next version and would appreciate if you could review it again.
Thanks,
Pingfan
