Not a big deal. Most SRF users should have a BIOS with the workaround by now.

If I interpret this question as "what is your motivation precisely", I would
answer this way:
* Because version 6.12 is LTS, there is a good chance that users of near-future
new platforms will run 6.12 on them.
* If a near-future platform happens to miss the firmware workaround for this
issue, having these patches in 6.12 will likely mean that most users are OK.
No other motivation.
Overall, I would categorize back-porting this patch-set to 6.12 as "nice to
have".
Thank you!
