It is not likely alpha will have 5-level page tables.

Replace usage of include/asm-generic/4level-fixup.h and implied
__ARCH_HAS_4LEVEL_HACK with include/asm-generic/pgtable-nop4d.h and adjust
page table manipulation macros and functions accordingly.


Not pgtable-nop4d.h, but pgtable-nopud.h. Also in subject.
