Revision ea424055b771a165c9abd3ae109255a3b825c745 authored by Jan Beulich on 30 August 2006, 17:37:11 UTC, committed by Linus Torvalds on 30 August 2006, 23:05:15 UTC 
[PATCH] x86: Make backtracer fallback logic more bullet-proof
 
The unwinder fallback logic still had potential for falling through to
the legacy stack trace code without printing an indication (at once
serving as a separator) of this.

Further, the stack pointer retrieval for the fallback should be as
restrictive as possible (in order to avoid having the legacy stack
tracer try to access invalid memory). The patch tightens that, but
this could certainly be further improved.

Also making the call_trace command line option now conditional upon
CONFIG_STACK_UNWIND (as it's meaningless otherwise).
