Hi all,
As some of you have noticed, there's a TON of failure messages being
sent out for AMD gpu driver commits that are tagged for stable
backports. In short, you all are doing something really wrong with how
you are tagging these.
Hi Greg,
I got notifications about one KFD patch failing to apply on six branches
(6.10, 6.6, 6.1, 5.15, 5.10 and 5.4). The funny thing is, that you
already applied this patch on two branches back in May. The emails had a
suspicious looking date in the header (Sep 17, 2001). I wonder if there
was some date glitch that caused a whole bunch of patches to be re-sent
to stable somehow:

Subject: [PATCH] drm/amdkfd: don't allow mapping the MMIO HDP page
with large pages ...
On 6.1 and 6.6, the patch was already applied by you in May:
$ git log --pretty=fuller stable/linux-6.6.y --grep "drm/amdkfd: don't allow mapping the MMIO HDP page with large pages"

drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
...
On 6.10 it was already upstream.
On 5.4-5.15 it doesn't apply because of conflicts. I can resolve those
and send the fixed patches out for you.

Please fix it up to NOT have duplicates in multiple branches that end up
in Linus's tree at different times. Or if you MUST do that, then give
us a chance to figure out that it IS a duplicate. As-is, it's not
working at all, and I think I need to just drop all patches for this
driver that are tagged for stable going forward and rely on you all to
provide a proper set of backported fixes when you say they are needed.
Again, what you are doing today is NOT ok and is broken. Please fix.
