  cgroup: rstat: relax NMI guard after switch to try_cmpxchg (2026-05-20 09:44:35 -1000)

----------------------------------------------------------------
cgroup: Fixes for v7.1-rc4

Two rstat fixes:

- Out-of-bounds access in the css_rstat_updated() BPF kfunc when called
  with an unchecked user-supplied cpu.

- Over-strict NMI guard after the recent switch to try_cmpxchg left
  sparc and ppc64 unable to queue rstat updates from NMI.
