4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael Ellerman <mpe@xxxxxxxxxxxxxx> The backport of the RFI flush support, done by me, has a minor bug in that the code is inside an #ifdef CONFIG_HARDLOCKUP_DETECTOR, which is incorrect. This doesn't matter with common configs because we enable HARDLOCKUP_DETECTOR, but with future patches it will break the build. So fix it.
