To support Cooperative Memory Overcommitment (CMO), we need to check for failure from some of the tce hcalls. These changes for the pseries platform affect the powerpc architecture; patches for the other affected platforms are included in this patch. pSeries platform IOMMU code changes: * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and return an error. Architecture IOMMU code changes: * Calls to ppc_md.tce_build need to check return values and return DMA_MAPPING_ERROR for transient errors. Architecture changes: * struct machdep_calls for tce_build*_pSeriesLP functions need to change to indicate failure. * all other platforms will need updates to iommu functions to match the new calling semantics; they will return 0 on success. The other platforms default configs have been built, but no further testing was performed.
