v6.13-rc1 may give a lockdep splat when mounting /sys/fs/resctrl
(known CONFIG options to trigger this are:

PROVE_LOCKING && SELINUX && (EXT4 || BTRFS)

but there may be others).

These resctrl patches are not directly dependent on the fixes that
went into -rc2:

22465bbac53c blk-mq: move cpuhp callback registering out of q->sysfs_lock
4bf485a7db5d blk-mq: register cpuhp callback after hctx is added to xarray table

they work ok on top of -rc1 (as long as you ignore the lockdep splat).

I see you already have one patch in TIP x86/cache on top of v6.13-rc1

Your choice whether to rebase that to -rc2 and then apply my series. It
might make testing smoother.
