Subject: Re: [PATCH 0/8] unwind, arm64: add sframe unwinder for kernel

Not only does objdump show that func_start_addr all 0s, but the
func_start_addr in the kernel module's sframe table is also incorrect. I'll
prepare a repro so we can investigate this.

Great! Thanks.
This will be helpful for comparing the values from the sframe table with
the values we obtain at runtime
