Frederic Weisbecker 61e67fb9d3 perf/x86-64: Use frame pointer to walk on irq and process stacks 
We were using the frame pointer based stack walker on every
contexts in x86-32, but not in x86-64 where we only use the
seven-league boots on the exception stacks.

Use it also on irq and process stacks. This utterly accelerate
the captures.
