Masami Hiramatsu 4d0d3ac1ec kprobes/x86: Disable preemption in ftrace-based jprobes 
[ Upstream commit 5bb4fc2d86 ]

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.
