Besides using pr_info() to print the linkdown status for a plug-in slot, add extra indication that this is expected if the slot is empty. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

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.

If we are rebooting (e.g. via kexec) then the PCI RC link may already be up. In that case, we don't want to do the software fixup to force the link up, since that can degrade it to Gen1. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

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.

Most architectures implement this in exactly the same way. Instead of having each architecture duplicate this function, provide a single implementation in the core and make it a weak symbol so that it can be overridden on architectures where it is required.

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.
