[ Upstream commit 9d3fcb28f9b9750b474811a2964ce022df56336e ]

This reverts commit d60cd06331a3566d3305b3c7b566e79edf4e2095.

This patch causes a panic when rebooting my Dell Poweredge r440. I do
not have the full panic log as it's lost at that stage of the reboot and
I do not have a serial console. Reverting this patch makes my system
able to reboot again.
