Re: [PATCH] powerpc/stacktrace: Fix spurious "stale" traces in raise_backtrace_ipi()

In raise_backtrace_ipi() we iterate through the cpumask of CPUs, sending
each an IPI asking them to do a backtrace, but we don't wait for the
backtrace to happen.

We then iterate through the CPU mask again, and if any CPU hasn't done
the backtrace and cleared itself from the mask, we print a trace on its
behalf, noting that the trace may be "stale".

Applied to powerpc/next.
