[PATCH 0/8] pseries/iommu: bug-fixes and cleanups for dynamic dma windows

[Nishanth Aravamudan]

This series of patches attempts to cleanup and fix some bugs related to
dynamic dma windows and kexec/kdump. They build on the three patches I
have submitted most recently:

powerpc: fix kexec with dynamic dma windows
	http://patchwork.ozlabs.org/patch/94445/
pseries/iommu: restore iommu table pointer when restoring iommu ops
	http://patchwork.ozlabs.org/patch/94909/
pseries/iommu: use correct return type in dupe_ddw_if_already_created
	http://patchwork.ozlabs.org/patch/95184/

The full series has been successfully tested with kdump/kexec on pseries
machine.

Milton Miller (8):
  pseries/iommu: add additional checks when changing iommu mask
  pseries/iommu: remove ddw property when destroying window
  pseries/iommu: find windows after kexec during boot
  pseries/iommu: cleanup ddw naming
  powerpc: override dma_get_required_mask by platform hook and ops
  dma-mapping: add get_required_mask if arch overrides default
  powerpc: use the newly added get_required_mask dma_map_ops hook
  powerpc: tidy up dma_map_ops after adding new hook
