Subject[PATCH 0/3] Fix two PEIe hotplug issues
Fix PCIe Hotplug so that it works with ExpressCard slots on Dell notebooks
(and others?) in conjunction with the modparam of pciehp_force=1.

The PCIe Hotplug driver has two issues when used on Dell notebooks
which lack ACPI BIOS support for PCIe hotplug:

1. The driver does not recognise cards that were inserted
prior to the driver being modprobe'd.

2. The driver stops functioning after a suspend/resume (RAM) cycle,
and needs to be rmmod'd and modprobe'd to get it working again.

This patch series addresses those issues, resulting in a completely
functional PCIe Hotplug driver for Dell notebooks, and possibly others
as well which may lack ACPI BIOS support for this.
Note that pciehp_force=1 is (still) required.

There are three patches in this series:

-- fixes problem number 1 (above).

-- preparation for the resume patch.

-- fixes problem number 2 (above).

diffstat summary for the three patches combined:
drivers/pci/hotplug/pciehp.h | 3
drivers/pci/hotplug/pciehp_core.c | 23 +++
drivers/pci/hotplug/pciehp_ctrl.c | 2
drivers/pci/hotplug/pciehp_hpc.c | 185 +++++++++++++++-------------
