Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop" (2024-09-15 02:49:33 -0400)
----------------------------------------------------------------
Do not always honor guest PAT on CPUs that support self-snoop.
This triggers an issue in the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM. The revert lets video
RAM use the WB memory type instead of the slower UC memory type.
