Subject: [PATCH v2 0/8] PCI: pciehp: Rework hotplug interrupt routine

This is mostly Mayurkumar's work from [1] and [2].  I split [2] into two
patches and reworked it to keep the enclosing loop around the pciehp ISR.

The patches I added are trivial ones to clarify variable names, make dmesg
messages consistent, and remove useless code.
