Subject: [PATCH -tip v4] Enable optprobe on preepmtive kernel

This patch enables optprobe even with CONFIG_PREEMPT. The
previous patch is  https://lkml.org/lkml/2017/9/19/159 .

Sorry for taking so long to update.
I've update the patch description according to Ingo's comment
but the code is same.

Thank you,
