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?
