Jan Beulich c33bd9aac0 [PATCH] i386/x86-64: fall back to old-style call trace if no unwinding 
If no unwinding is possible at all for a certain exception instance,
fall back to the old style call trace instead of not showing any trace
at all.

Also, allow setting the stack trace mode at the command line.

Jan Beulich 4552d5dc08 [PATCH] x86_64: reliable stack trace support 
These are the generic bits needed to enable reliable stack traces based
on Dwarf2-like (.eh_frame) unwind information. Subsequent patches will
enable x86-64 and i386 to make use of this.

Thanks to Andi Kleen and Ingo Molnar, who pointed out several possibilities
for improvement.
