Another one, not sure if related to the last one.
These are easy to trigger, but not reproducible at all even with pretty
exact syscall trace matches. So I'm not sure what's going on.

[ 2696.228000] BUG: soft lockup - CPU#0 stuck for 23s! [perf_fuzzer:10256]
[ 2696.22800
Triggered by the perf_fuzzer on a core2 machine, 3.14-rc6.
Hopefully the trace_do_page_fault in the stack trace is incidental and not
showing that something was missed with the recent page fault tracing
fixes.
