This reverts commit68db9bc814. Yinghai reported that the following manual hotplug sequence: # echo 0 > /sys/bus/pci/slots/8/power # echo 1 > /sys/bus/pci/slots/8/power worked in v4.9, but fails in v4.10-rc1, and that reverting68db9bc814("PCI: pciehp: Add runtime PM support for PCIe hotplug ports") makes it work again.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
