Didn't take long :(

mm/memory.c: In function 'zap_pud_range':
mm/memory.c:1216: error: implicit declaration of function 'pud_trans_huge'
mm/memory.c:1217: error: 'HPAGE_PUD_SIZE' undeclared (first use in this function)

and, midway:

include/linux/mm.h:348: error: redefinition of 'pud_devmap'
include/asm-generic/pgtable.h:684: note: previous definition of 'pud_devmap' was here

Please run x86_64 allnoconfig at each step of the series, fix and
respin? It only takes 30s to compile.
