Linus,

Please pull the latest sched/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-2022-05-23

   # HEAD: 991d8d8142cad94f9c5c05db25e67fa83d6f772a topology: Remove unused cpu_cluster_mask()

Scheduler changes in this cycle were:

 - Updates to scheduler metrics:

    - PELT fixes & enhancements
    - PSI fixes & enhancements
    - Refactor cpu_util_without()

 - Updates to instrumentation/debugging:

    - Remove sched_trace_*() helper functions - can be done via debug info
    - Fix double update_rq_clock() warnings

 - Introduce & use "preemption model accessors" to simplify some of
   the Kconfig complexity.

 - Make softirq handling RT-safe.

 - Misc smaller fixes & cleanups.

 Thanks,

	Ingo

Note that the above is a v5.18 based shortlog and diffstat, but because the 
RCU tree deep-merged one of the scheduler commits that introduced better, 
Kconfig-invariant preemption model accessors:

   cfe43f478b79 preempt/dynamic: Introduce preemption model accessors

... and you merged the RCU tree already, so you'll get this shortlog & 
diffstat:

Ah, this one:

cfe43f478b79 ("preempt/dynamic: Introduce preemption model accessors")

Please accept my apologies for the disruption.  This commit was needed
to be able to properly handle CONFIG_PREEMPT_DYNAMIC=y kernels booting
with preempt=none or preempt=voluntary.  But I should have called this
out in my pull request, and failed to do so.  Again, please accept my
apologies for the disruption.

							Thanx, Paul
