This is to avoid pseries calling into powernv code. The first patch changes data structure a bit, the second is cut-n-paste without changing logic or data structures.
This is not changing symbol names as the NVIDIA UVM driver calls some of them (pnv_npu2_init_context, pnv_npu2_destroy_context, pnv_pci_get_npu_dev, pnv_npu2_handle_fault). This is based on sha1 574823bf Linus Torvalds "Change mincore() to count "mapped" pages rather than "cached" pages". Please comment. Thanks.
