Sure. I'm actually not even sure that for a [PATCH]-quality thing this
cross-cutting commit even makes sense - once we've decided on the
general way to solve this problem, perhaps the changes should just be
part of the commit that needs them?

Right, that sounds better.

It feels messy to have a patch that "does multiple things", but on the
other hand it might be annoying to review a patch that says "make a
load of random changes across the kernel, which are needed at various
points in various upcoming patches, trust me".

Do you have any opinion on that?

You're absolutely right - we do things when we need them and not before.
Otherwise, often times things get done preemptively and then forgotten only
for someone to notice way later and undo them again.

(BTW, since a comment you made on another series (can't find it on
Lore...), I've changed my writing style to avoid stuff like this in
comments & commit messages in general, but this text all predates
that. I'll do my best to sort all that stuff out before I send
anything as a [PATCH].)

Thanks!

Btw, good and funny way to use "[PATCH]-quality" to mean non-RFC. :-P

Oh, I didn't notice your update until now. But yeah I also couldn't
reproduce it on a Sapphire Rapids machine and on QEMU with this patch
applied on top of tip/master (37bc915c6ad0f).

Yeah, it feels like toolchain-related but I can't put my finger on it yet.
We'll see if and when this thing will re-surface its ugly head...

:-)

Thx.
