memory allocated for intermediate levels. When multilevel TCE table is
requested, WARN_ON in tce_iommu_create_table() prints a warning.

This adds an additional counter to pnv_pci_ioda2_table_do_alloc_pages()
to count actually allocated memory.

Sorry if it is a duplicate.


Stable?


No, this is for DDW patchset I recently posted and which did not get to any 
release yet.
