Subject: faddr2line issue

Hi Josh,

I am finding that for a few mainline kernel releases that faddr2line 
does seem to be working:

./scripts/faddr2line vmlinux  sas_discover_domain+0x4dc/0x560
sas_discover_domain+0x4dc/0x560:
fs mm ??:0

This is on my arm64 system. I have not tried another arch. Are there any 
known issues?

Maybe I'm using it incorrectly... I can go back and see when this 
stopped working for me.

Cheers,
John
