Note that this patch breaks in various cross-builds - here's the Alpha defconfig
build:
/home/mingo/tip/kernel/sched/debug.c: In function 'print_rt_rq':
/home/mingo/tip/kernel/sched/debug.c:556:60: error: 'struct rt_rq' has no member
named 'rt_nr_migratory'
SEQ_printf(m, " .%-30s: %lu\n", #x, (unsigned long)(rt_rq->x))
^
/home/mingo/tip/kernel/sched/debug.c:33:17: note: in definition of macro
'SEQ_printf'
seq_printf(m, x); \
