      [POWERPC] Refactor 64 bits DMA operations · 12d04eef
      Benjamin Herrenschmidt authored
      
      
      This patch completely refactors DMA operations for 64 bits powerpc. 32 bits
      is untouched for now.
      
      We use the new dev_archdata structure to add the dma operations pointer
      and associated data to struct device. While at it, we also add the OF node
      pointer and numa node. In the future, we might want to look into merging
      that with pci_dn as well.
      
      The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced
      by a set of generic iommu and direct DMA ops (non PCI specific) that can be
      used by bus types. The toplevel implementation is now inline.

      [POWERPC] Make pci_read_irq_line the default · f90bb153
      Benjamin Herrenschmidt authored
      
      
      This patch reworks the way IRQs are fixed up on PCI for arch powerpc.
      
      It makes pci_read_irq_line() called by default in the PCI code for
      devices that are probed, and add an optional per-device fixup in
      ppc_md for platforms that really need to correct what they obtain
      from pci_read_irq_line().
      
      It also removes ppc_md.irq_bus_setup which was only used by pSeries
      and should not be needed anymore.
      
      I've also removed the pSeries s7a workaround as it can't work with
      the current interrupt code anyway. I'm trying to get one of these
      machines working so I can test a proper fix for that problem.
      
      I also haven't updated the old-style fixup code from 85xx_cds.c
      because it's actually buggy :) It assigns pci_dev->irq hard coded
      numbers which is no good with the new IRQ mapping code. It should
      at least use irq_create_mapping(NULL, hard_coded_number); and possibly
      also set_irq_type() to set them as level low.
