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
----------------------------------------------------------------
