Hi,

This patch series consists of 2 patches. It is based on v6.9-rc4.

- A fix aiming for v6.9-rc (to be backported to stable kernels):
  "sched: Add missing memory barrier in switch_mm_cid"

- An improvement patch aiming for v6.10:
  "sched: Move mm_cid code from sched.h to core.c"

Thanks,

Mathieu

I've applied the first patch to tip:sched/urgent, and will queue up the 
code movement patch in the scheduler tree for v6.10, thanks Mathieu!
