x86/pat: Simplify the PAT programming protocol (2024-02-20 14:40:51 +0100)
---------------------------------------------------------------- - Relax the PAT MSR programming which was unnecessarily using the MTRR programming protocol of disabling the cache around the changes. The reason behind this is the current algorithm triggering a #VE exception for TDX guests and unnecessarily complicating things
