LR compute WA

Hi,

We have some reports of long compute jobs on APUs hanging the system. This has been root caused and a workaround has been introduced in the mainline kernel. I didn't CC stable on the original W/A because I wanted to make sure we've had enough time to test it didn't have unintended side effects.

I feel comfortable with the testing at this point and I think it's worth bringing back to any stable kernels it will apply to 6.12.y and newer. The commit is:

Thanks,
