PCI: Remove unused pci_dma_burst_advice()

pci_dma_burst_advice() was added by e24c2d963a60 ("[PATCH] PCI: DMA bursting advice") but apparently never used. Remove it. Signed-off-by: Bjorn Helgaas Acked-by: Michal Simek # microblaze CC: David S. Miller

irq_remapping: Clean up unused MSI related code

2015-04-24T13:36:49+00:00

Now MSI interrupt has been converted to new hierarchical irqdomain interfaces, so remove legacy MSI related code and interfaces.

PCI: Turn pcibios_penalize_isa_irq() into a weak function

2014-05-27T22:23:58+00:00

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA is not used by some architectures. Make pcibios_penalize_isa_irq() a __weak function to simplify the code. This removes the need for new platforms to add stub implementations of pcibios_penalize_isa_irq().

x86/PCI: Drop return value of pcibios_scan_root()

2014-02-03T17:38:29+00:00

Nobody really uses the return value of pcibios_scan_root() (one place uses it to control a printk, but the printk is not very useful). This converts pcibios_scan_root() to a void function. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J. Wysocki

x86/PCI: Merge pci_scan_bus_on_node() into pcibios_scan_root()

2014-02-03T17:38:23+00:00

pci_scan_bus_on_node() is only called by pcibios_scan_root(). This merges pci_scan_bus_on_node() into pcibios_scan_root() and removes pci_scan_bus_on_node(). Signed-off-by: Bjorn Helgaas Acked-by: Rafael J. Wysocki

x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_with_sysdata()

2014-02-03T17:38:11+00:00

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.
