      powerpc: Merge 32 and 64-bit dma code · 4fc665b8
      Becky Bruce authored 
      
We essentially adopt the 64-bit dma code, with some changes to support
32-bit systems, including HIGHMEM.  dma functions on 32-bit are now
invoked via accessor functions which call the correct op for a device based
on archdata dma_ops.  If there is no archdata dma_ops, this defaults
to dma_direct_ops.

In addition, the dma_map/unmap_page functions are added to dma_ops
because we can't just fall back on map/unmap_single when HIGHMEM is
enabled. In the case of dma_direct_*, we stop using map/unmap_single
and just use the page version - this saves a lot of ugly
ifdeffing.  We leave map/unmap_single in the dma_ops definition,
though, because they are needed by the iommu code, which does not
implement map/unmap_page.  Ideally, going forward, we will completely
eliminate map/unmap_single and just have map/unmap_page, if it's
workable for 64-bit.

      [POWERPC] Don't try to allocate resources for a Freescale POWERPC PHB · 2052d6d2
      Kumar Gala authored 
      
The Freescale PCI PHBs actual report back values in the BAR registers
this causes issues in that we try to allocate resources for them
and will get error messages like the following on MPC8544 DS:

PCI: Failed to allocate mem resource #1:80000000@0 for 0000:00:00.0

To address this if we are class PCI_CLASS_PROCESSOR_POWERPC, a normal
header type, and the PHB we clear out all the resources.

      PCI: Make pcibios_add_platform_entries() return errors · a2cd52ca
      Michael Ellerman authored 
      
Currently pcibios_add_platform_entries() returns void, but could fail,
so instead have it return an int and propagate errors up to
pci_create_sysfs_dev_files().

Fixes:
arch/powerpc/kernel/pci_64.c: In function 'pcibios_add_platform_entries':
arch/powerpc/kernel/pci_64.c:878: warning: ignoring return value of
	'device_create_file', declared with attribute warn_unused_result
arch/powerpc/kernel/pci_32.c: In function 'pcibios_add_platform_entries':
  arch/powerpc/kernel/pci_32.c:1043: warning: ignoring return value of
	'device_create_file', declared with attribute warn_unused_result

      [POWERPC] Fix STRICT_MM_TYPECHECKS · 69d48b40
      David Gibson authored 
      
Since we don't have it active by default, the STRICT_MM_TYPECHECKS
option has bitrotted again.  This patch fixes a couple of simple build
fixes if the option is selected.  First, pud_t mustn't be defined in
page.h on 32-bit systems, because it conflicts with the version in the
generic pud-folding code.  Second, pci_32.c is missing a __pgprot()
wrapper call.  Third, a couple of PS3 files use constants of type
pgprot_t when they need the raw values, we add pgprot_val() calls to
fix this.
