hugetlbfs: architecture header cleanup
This patch moves all architecture functions for hugetlb to architecture header files (include/asm-foo/hugetlb.h) and converts all macros to inline functions. It also removes (!) ARCH_HAS_HUGEPAGE_ONLY_RANGE, ARCH_HAS_HUGETLB_FREE_PGD_RANGE, ARCH_HAS_PREPARE_HUGEPAGE_RANGE, ARCH_HAS_SETCLEAR_HUGE_PTE and ARCH_HAS_HUGETLB_PREFAULT_HOOK. Getting rid of the ARCH_HAS_xxx #ifdef and macro fugliness should increase readability and maintainability, at the price of some code duplication. An asm-generic common part would have reduced the loc, but we would end up with new ARCH_HAS_xxx defines eventually.
