x86 PCI: call dmi_check_pciprobe()
this change: | commit 08f1c192c3c32797068bfe97738babb3295bbf42 | Author: Muli Ben-Yehuda <muli@il.ibm.com> | Date: Sun Jul 22 00:23:39 2007 +0300 | | x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata | | This patch introduces struct pci_sysdata to x86 and x86-64, and | converts the existing two users (NUMA, Calgary) to use it. | | This lays the groundwork for having other users of sysdata, such as | the PCI domains work. | | The Calgary bits are tested, the NUMA bits just look ok. replaces pcibios_scan_root with pci_scan_bus_parented... but in pcibios_scan_root we have a DMI check: dmi_check_system(pciprobe_dmi_table); when when have several peer root buses this could be called multiple times (which is bad), so move that call to pci_access_init().
