The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage sites. The conversion helper functions are kept around to avoid conflicts in next and will be removed after merging into mainline. Coccinelle assisted conversion. No functional change.

We don't need anything arch-specific in pcibios_enable_device(), so drop the arch implementation and use the default generic one. Note: pci_enable_resources() checks that r->parent is non-NULL, which basically checks that pci_claim_resource() or request_resource() has been called for each BAR. I don't see where that happens for tile, but this patch doesn't change that behavior, so if it worked before, it should still work.

This change sets the PCI devices' initial DMA capabilities conservatively and promotes them at the request of the driver, as opposed to assuming advanced DMA capabilities. The old design runs the risk of breaking drivers that assume default capabilities. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

Based on a patch by Jon Mason (see URL below). All users of pcie_bus_configure_settings() pass arguments of the form "bus, bus->self->pcie_mpss". The "mpss" argument is redundant since we can easily look it up internally. In addition, all callers check "bus->self" for NULL, which we can also do internally. This patch simplifies the interface and the callers. No functional change.

We can take advantage of the fact that bit 29 is hard-wired to zero in register TRIO_TILE_PIO_REGION_SETUP_CFG_ADDR. This is handy since at the moment we only allocate one 4GB region for vmalloc, and with this change we can allocate four or more TRIO MACs without using up all the vmalloc space.

To support PCIe devices with higher number of MSI-X interrupt vectors, e.g. 16 for the LSI RAID card, enhance the Gx RC stack to provide more MSI-X vectors by using the TRIO Scatter Queues, which provide 8 more vectors in addition to ~10 from the Map Mem regions.

This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Remove the __init annotations in order to keep pci_fixup_irqs() around after init (e.g. for hotplug). This requires the same change for the implementation of pcibios_update_irq() on all architectures. While at it, all __devinit annotations are removed as well, since they will be useless now that HOTPLUG is always on.

Yinghai Lu removed pci_bus.subordinate in pci-next, which meant that the tile-next changes to add tilegx PCI support don't build. This was expected (seen in linux-next) and this one-line fix is along the same lines as commit b918c62e for all other architectures.

This change uses the TRIO IOMMU to map the PCI DMA space and physical memory at different addresses. We also now use the dma_mapping_ops to provide support for non-PCI DMA, PCIe DMA (64-bit) and legacy PCI DMA (32-bit). We use the kernel's software I/O TLB framework (i.e. bounce buffers) for the legacy 32-bit PCI device support since there are a limited number of TLB entries in the IOMMU and it is non-trivial to handle indexing, searching, matching, etc. For 32-bit devices the performance impact of bounce buffers should not be a concern.
