Subject: trace: stop tracer in oops_enter()
X-Git-Tag: v2.6.31-rc6~77^2~1

trace: stop tracer in oops_enter()

If trace_printk_on_oops is set we lose interesting trace information
when the tracer is enabled across oops handling and printing. We want
the trace which might give us information _WHY_ we oopsed.
