Linux 5.18 Unifying Two More Portions Of AMD & Intel Code

Thanks to the nature of open-source and independently-controlled projects like the Linux kernel, there is already much code sharing among competitive hardware vendors in areas where applicable. Much of the Linux kernel's x86/x86_64 code is shared between AMD and Intel (and VIA, Centaur, and Hygon for that matter) where relevant while due to different supported features and implementation differences there is divergence at times. With Linux 5.18 there are two features currently with unique AMD and Intel code paths that are working towards more unification...
