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, from include/linux/bug.h:4, from include/linux/thread_info.h:11, from include/asm-generic/preempt.h:4, from arch/microblaze/include/generated/asm/preempt.h:1, from include/linux/preempt.h:18, from include/linux/spinlock.h:50, from include/linux/mmzone.h:7, from include/linux/gfp.h:5, from include/linux/slab.h:14, from mm/mmap.c:12: mm/mmap.c: In function 'exit_mmap': >> mm/mmap.c:2858:46: error: 'PUD_SHIFT' undeclared (first use in this function) round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> PUD_SHIFT); ^ include/asm-generic/bug.h:86:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^ mm/mmap.c:2858:46: note: each undeclared identifier is reported only once for each function it appears in round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> PUD_SHIFT); ^ include/asm-generic/bug.h:86:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^ As with <asm-generic/pgtable-nopud.h>, let's define PUD_SHIFT to PGDIR_SHIFT.
