Hi Stephen,

	next-20090925 randconfig build breaks on s390x, with CONFIG_AIO=n.

arch/s390/mm/pgtable.c: In function 's390_enable_sie':
arch/s390/mm/pgtable.c:282: error: 'struct mm_struct' has no member named 'ioctx_list'
arch/s390/mm/pgtable.c:298: error: 'struct mm_struct' has no member named 'ioctx_list'
make[1]: *** [arch/s390/mm/pgtable.o] Error 1

Reverting the below commit helps

    aio: ifdef fields in mm_struct

	->ioctx_lock and ->ioctx_list are used only under CONFIG_AIO.
