Subject: Re: [PATCH 0/3] ARC unwinder switch to .eh_frame

Hi Vineet,

Thank you for your patches. I applied them, and verified that
unwinding works with code that is compiled into the kernel image as
well as kernel modules.
I confirmed that the .eh_frame section is present and that the
.debug_frame section is absent. I also verified that the file size of
the .ko files are small enough for our embedded platform and that
unnecessary sections like .debug_info, .debug_line, .debug_str etc.
are also absent.
Is there anything else you want me to test?
Thanks
Daniel
