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. ---------------------------------------------------------------- Paolo Bonzini (1): Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop" arch/x86/kvm/mmu/mmu.c | 8 +++----- arch/x86/kvm/vmx/vmx.c | 10 ++++------ 2 files changed, 7 insertions(+), 11 deletions(-)
