My simpler method, however, forgot to add the extended CPU model to the patch revision, which lead to mismatches when determining whether TSA mitigation support is present. So add that forgotten extended model. Also, fix a backport mismerge which put tsa_init() where it doesn't belong. This is a stable-only fix and the preference is to do it this way because it is a lot simpler. Also, the Fixes: tag below points to the respective stable patch.
