From: Bjorn Helgaas <bhelgaas@...gle.com>
To: linux-pci@...r.kernel.org
Cc: linux-acpi@...r.kernel.org, x86@...nel.org,
linux-ia64@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 02/17] x86/PCI: Use pcibios_scan_root() instead of
pci_scan_bus_with_sysdata()
pci_scan_bus_with_sysdata() and pcibios_scan_root() are quite similar:
pci_scan_bus_with_sysdata
pci_scan_bus_on_node(..., &pci_root_ops, -1)
pcibios_scan_root
pci_scan_bus_on_node(..., &pci_root_ops, get_mp_bus_to_node(busnum))
get_mp_bus_to_node() returns -1 if it couldn't find the node number, so
this removes pci_scan_bus_with_sysdata() and uses pcibios_scan_root()
instead.
