It turns out, it's just not worth to add bits to the core just for hisi_sas_v2 driver. I dropped those changes. BTW, this series is based on linux-block/for-next from 2024-11-11. Not sure if this is the right base, if not please let me know which branch I should use. Original cover letter: These patches were part of 'honor isolcpus configuration' [1] series. To simplify the review process I decided to send this as separate series because I think it's a nice cleanup independent of the isolcpus feature.
