This is a split out of v1 series "Reduce ifdef mess in hugetlbpage.c and slice.c"

The main purpose of this series is to reduce the amount of #ifdefs in
hugetlbpage.c by moving subarch specific stuff in dedicated header files.

This series also drops all CONFIG_PPC_64K_PAGES related code in book3e
as it cannot be selected.
