Subject[RFC PATCH 00/11] ppc: enable dynamic dma window support
Date
Hi,

The following series, which builds upon the series of cleanups I posted
on 9/15 as "ppc iommu cleanups", enables the pseries firmware feature
dynamic dma windows. This feature will allow future devices to have a
64-bit DMA mapping covering all memory, coexisting with a smaller IOMMU
window in 32-bit PCI space.

Comments requested and welcome!

Nishanth Aravamudan (11):
macio: ensure all dma routines get copied over
ppc: allow direct and iommu to coexist
ppc: Create ops to choose between direct window and iommu based on
device mask
ppc: add memory_hotplug_max
ppc: do not search for dma-window property on dlpar remove
ppc: checking for pdn->parent is redundant
ppc/iommu: do not need to check for dma_window == NULL
ppc/iommu: remove unneeded pci_dma_bus_setup_pSeriesLP
ppc/iommu: pass phb only to iommu_table_setparms_lpar
ppc/iommu: add routines to pseries iommu to map tces 1-1
ppc: add dynamic dma window support
