I am trying to get the call trace of a process by tracing the return
addresses on the stack. To get the correct location of the return address
I need to know whether the kernel is being compiled with frame pointer
because this will affect the offset of return address on the stack.

Sad to say, you cannot. This is an extract from the kdb patch

You want #endif here.

I think you've been looking at some of the ARM code. Yes, we do manipulate
the CFLAGS
