Backport 36569780b0d6 ("sched: Change nr_uninterruptible type to unsigned long") to linux-stable

Hi maintainers,

Please consider backporting this upstream commit:

36569780b0d6 ("sched: Change nr_uninterruptible type to unsigned long”)

into all stable branches newer than (and including) linux-5.14.y.

This fixes an overflow bug introduced in commit:

e6fe3f422be1 ("sched: Make multiple runqueue task counters 32-bit”)

which was merged into 5.14.

I forgot to tag the original patch for inclusion into stable - I apologize for the oversight.

The patch should apply cleanly to all versions - let me know if you’d like me to send a separate patch for stable.

Thanks very much, Aruna
