Once I've run some tests on this branch the patches there will be added to the platform-drivers-x86/for-next branch and eventually will be included in the pdx86 pull-request to Linus for the next merge-window. I'll also cherry-pick these into the pdx86 fixes branch and add them to my next 5.18 fixes pull-req to Linus.
