From 0df18ff366853cdf31e5238764ec5c63e6b5a398 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 14 Apr 2008 15:40:37 -0700 Subject: [PATCH] x86 PCI: call dmi_check_pciprobe() this change: | commit 08f1c192c3c32797068bfe97738babb3295bbf42 | Author: Muli Ben-Yehuda | 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().
