UBSAN: shift-out-of-bounds in .../intel_opregion.c:388:15

[Daniel van Vugt]

This seems to happen at boot on all 11th gen Intel systems I've seen. But also on a 10th gen Intel system seen in other bug reports.

Fixed upstream it seems:

The aforementioned commit is now in the jammy kernel. No wonder I hadn't seen this bug in a while.
