powerpc: define support for 16G hugepages
The huge page size is defined for 16G pages. If a hugepagesz of 16G is specified at boot-time then it becomes the huge page size instead of the default 16M. The change in pgtable-64K.h is to the macro pte_iterate_hashed_subpages to make the increment to va (the 1 being shifted) be a long so that it is not shifted to 0. Otherwise it would create an infinite loop when the shift value is for a 16G page (when base page size is 64K).
