6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Brost <matthew.brost@intel.com>
commit 703ccb63ae9f7444d6ff876d024e17f628103c69 upstream.
In unplug_oldest_pwq(), the first inactive work item on the
pool_workqueue is activated correctly. However, if multiple inactive
works exist on the same pool_workqueue, subsequent works fail to
activate because wq_node_nr_active.pending_pwqs is empty — the list
insertion is skipped when the pool_workqueue is plugged.
Fix this by checking for additional inactive works in
unplug_oldest_pwq() and updating wq_node_nr_active.pending_pwqs
accordingly.
Fixes: 4c065dbce1e8 ("workqueue: Enable unbound cpumask update on ordered workqueues")

Of course, we still have the many missing safety comments Clippy
warnings we expected from last time, i.e. the ones that we discussed
recently, e.g.:
warning: unsafe block missing a safety comment
--> rust/kernel/init/macros.rs:1015:25

I just wanted to point out that the revert of "PCI: Enable ACS after
configuring IOMMU for OF platforms" is missing here despite being queued
in the 6.1 & 6.6 rcs (it is meant to be reverted from 6.12 as well). I
noticed when updating to 6.12.82-rc1 today as I was bit by the
regression (all my IOMMU groups messed up).
The revert for 6.12 is in fact here:
https://lore.kernel.org/stable/20260320172335.29778-1-john@kernel.doghat.io/
but unfortunately easily missed as shown by the confusion here (same
thread):
https://lore.kernel.org/stable/99426bd8-32e5-4246-9d3b-772e136bc078@leemhuis.info/
subsequently clarified by the patch author here (also same thread):
https://lore.kernel.org/stable/5hng5r6q525scbclramuv2h2hphljbcsscwohvrs7teuedgfvl@ncr7tqhr4l4z/
Other than that 6.12.82-rc1 boots and runs fine for me on the one AMD
Ryzen system I've tried it on.
Thanks,
Eddie

That was not obvious at all, please don't make us dig through email
threads to know what to and not to apply, it doesn't scale when dealing
with the email volume we get.
Can someone resend that patch, properly marked fro 6.12, so we know to
apply it there?
thanks,
greg k-h

Adding Manivannan Sadhasivam who is the author of the revert that is in
the 5.10, 5.15, 6.1 and 6.6 queues right now.
Manivannan, not sure if you are able to provide an updated patch for
6.12 where the revert is missing right now?
FWIW I applied the patch at
https://lore.kernel.org/stable/20260320172335.29778-1-john@kernel.doghat.io/
on top of 6.12.82-rc1 today and booted on an AMD system to test. It has
context issues but still applies fine, and I can confirm that my IOMMU
groups are no longer messed up. As a result have been able to pass
through 2 separate PCI cards to 2 separate VMs which I am unable to do
without the revert.
