[PATCH 00/20] PCI root complex changes for tile architecture

[Chris Metcalf <cmetcalf@tilera.com>]

These changes add new features and fix bugs in the Tilera PCI
root complex subsystem.  Among the new tilegx features are support
for I/O space access, more MXI-X interrupt vectors, and support for
TRIO 0 MAC 0 on Gx72 systems.

Chris Metcalf (20):
  tile PCI RC: cleanups for tilepro PCI RC
  tile PCI RC: tilepro conflict with PCI and RAM addresses
  tile PCI RC: support pci=off boot arg for tilepro
  tile PCI RC: tweak the the pcie_rc_delay support
  tile PCI RC: handle case that PCI link is already up
  tile: support LSI MEGARAID SAS HBA hybrid dma_ops
  tile PCI RC: support more MSI-X interrupt vectors
  tile PCI RC: gentler warning for missing plug-in PCI
  tile PCI RC: support I/O space access
  tile PCI DMA: handle a NULL dev argument properly
  tile PCI RC: restructure TRIO initialization
  tile PCI RC: eliminate pci_controller.mem_resources field
  tile PCI RC: include pci/pcie/Kconfig
  tile PCI RC: bomb comments and whitespace format
  tile PCI RC: use proper accessor function
  tile PCI RC: add dma_get_required_mask()
  tile PCI DMA: fix bug in non-page-aligned accessors
  tile PCI RC: support PCIe TRIO 0 MAC 0 on Gx72 system
  tile PCI RC: reduce driver's vmalloc space usage
  tile PCI RC: remove stale include of linux/numa.h
