Keir, while the corresponding code has been in place for a very long time, I still stumbled across MSR_K7_HWCR being written for that purpose in two places: c/s 6382 introduced command line controllable behavior, while c/s 8831 added code to do the adjustment unconditionally. Imo one of the two changes should be removed again. What do you think?
