[PATCH] PCI Hotplug: add common acpi functions to core
shpchprm_acpi.c and pciehprm_acpi.c are nearly identical. In addition, there are functions in both these files that are also in acpiphp_glue.c. This patch will remove duplicate functions from shpchp, pciehp, and acpiphp and move this functionality to pci_hotplug, as it is not hardware specific. Get rid of shpchprm* and pciehprm* files since they are no longer needed. shpchprm_nonacpi.c and pciehprm_nonacpi.c are identical, as well as shpchprm_legacy.c and can be replaced with a macro. This patch also changes acpiphp to use the common hpp code. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
