Masami Hiramatsu 8633eec0ee kprobes/x86: Disable preemption in ftrace-based jprobes ...

[ Upstream commit 5bb4fc2d8641219732eb2bb654206775a4219aca ]

Disable preemption in ftrace-based jprobe handlers as
described in Documentation/kprobes.txt:

  "Probe handlers are run with preemption disabled."

This will fix jprobes behavior when CONFIG_PREEMPT=y.
