These definitions were repeated by all architectures, with small variations. Consolidate the common definitons in machine independent code and use bitset(9) macros for manipulation. Many opportunities for deduplication remain in the machine dependent minidump logic. The only intended functional change is increasing the bit index type to vm_pindex_t, allowing the indexing of pages with address of 8 TiB and greater.
