[PATCH] freepgt: remove arch pgd_addr_end
ia64 and sparc64 hurriedly had to introduce their own variants of
pgd_addr_end, to leapfrog over the holes in their virtual address spaces which
the final clear_page_range suddenly presented when converted from pgd_index to
pgd_addr_end. But now that free_pgtables respects the vma list, those holes
are never presented, and the arch variants can go.
