Subject: [PATCH 0/3] sched/numa: Update numa_balancing stats in /proc

Recent changes to numa balancing like adding group faults, merging
numa_faults and numa_mem_faults have not been reflected in /proc.

Hence some of the numa_balancing information is not exposed or displays
wrong info. This patchset tries to correct it.

Before change: /proc/pid/sched
clock-delta                                  :                   12
mm->numa_scan_seq                            :                   34
numa_migrations, 1
numa_faults_memory, 0, 0, 1, 0, -1
numa_faults_memory, 1, 0, 0, 0, -1
numa_faults_memory, 0, 1, 0, 0, -1
numa_faults_memory, 1, 1, 0, 0, -1
numa_faults_memory, 0, 2, 0, 0, -1
numa_faults_memory, 1, 2, 0, 0, -1
numa_faults_memory, 0, 3, 0, 0, -1
numa_faults_memory, 1, 3, 0, 0, -1

After change: /proc/pid/sched
clock-delta                                  :                   12
mm->numa_scan_seq                            :                   34
numa_pages_migrated                          :                    1
numa_preferred_nid                           :                    0
total_numa_faults                            :                 2627
current_node=0, numa_group_id=6958
numa_faults node=0 task_private=1344 task_shared=0 group_private=1344 group_shared=0
numa_faults node=1 task_private=641 task_shared=65 group_private=641 group_shared=65
numa_faults node=2 task_private=512 task_shared=0 group_private=512 group_shared=0
numa_faults node=3 task_private=64 task_shared=1 group_private=64 group_shared=1

  sched: Move print_cfs_rq declaration to kernel/sched/sched.h
  sched/numa: Show numa_group id in sched_debug task listings
  sched/numa: Fix numabalancing stats in /proc/pid/sched
