Having to maintain a per-system allowlist is burdensome and confusing
for users, drop it.

I propose to keep this in -next for two cycles or so to make sure it
does not break anything.

I think dropping this is a good idea (given the current experience with
the driver), but keeping the dropping of the list in -next for 2 cycles
is somewhat tricky. Normally once the final e.g. 6.3 is released I take
the pdx86/for-next branch *as-is* and use that to send a pull-req to
Linus, so that Linus gets send a hash which has been tested in linux-next
for a while before sending it to him.

Dropping this patch at that point would mean generating a new hash,
which is a bit meh. I can do that but I would prefer to just limit
testing to 1 full cycle.

Maybe you can send me a non RFC version of this patch once 6.4-rc1 is out?
Then I can add that to for-next right away and then we can get a full
cycle of -next testing that way.

Would that work for you?

Regards,

Hans
