Tom 6e46e21c42 Kernel: Implement Page Attribute Table (PAT) support and Write-Combine
This allows us to enable Write-Combine on e.g. framebuffers,
significantly improving performance on bare metal.

To keep things simple we right now only use one of up to three bits
(bit 7 in the PTE), which maps to the PA4 entry in the PAT MSR, which
we set to the Write-Combine mode on each CPU at boot time.
