Subject: linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from kernel/sched/build_utility.c:72:
kernel/sched/debug.c:341:57: warning: integer overflow in expression of type 'long int' results in '-100663296' [-Woverflow]
  341 | static unsigned long fair_server_period_max = (1 << 22) * NSEC_PER_USEC; /* ~4 seconds */
      |                                                         ^

Introduced by commit

  d741f297bcea ("sched/fair: Fair server interface")

This is a 32 bit build.
