Hi,
With the commit reverted, the patch doesn't apply. Without revert, kernel (patch applied) doesn't boot and I can't see any message.
Let me show you my PAT values (the commit reverted)
# dmesg | grep PAT [ 0.000000] x86 PAT enabled: cpu 0, old 0x0, new 0x7010600070106 [ 0.314631] x86 PAT enabled: cpu 3, old 0x0, new 0x7010600070106 [ 0.314703] x86 PAT enabled: cpu 1, old 0x0, new 0x7010600070106 [ 0.314780] x86 PAT enabled: cpu 2, old 0x0, new 0x7010600070106 [ 0.314852] x86 PAT enabled: cpu 4, old 0x0, new 0x7010600070106 [ 0.314923] x86 PAT enabled: cpu 0, old 0x0, new 0x7010600070106 [ 0.314997] x86 PAT enabled: cpu 6, old 0x0, new 0x7010600070106 [ 0.315069] x86 PAT enabled: cpu 7, old 0x0, new 0x7010600070106 [ 0.315142] x86 PAT enabled: cpu 5, old 0x0, new 0x7010600070106
