Subject: mm, asm-generic: define PUD_SHIFT in <asm-generic/4level-fixup.h>
If an architecure uses <asm-generic/4level-fixup.h>, build fails if we
try to use PUD_SHIFT in generic code:
In file included from arch/microblaze/include/asm/bug.h:1:0,

round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> PUD_SHIFT);

int __ret_warn_on = !!(condition); \
^
As with <asm-generic/pgtable-nopud.h>, let's define PUD_SHIFT to
PGDIR_SHIFT.
