Haozhong Zhang b8d7044bcf x86/mm: add a function to check if a pfn is UC/UC-/WC ... Check whether the PAT memory type of a pfn cannot be overridden by MTRR UC memory type, i.e. the PAT memory type is UC, UC- or WC. This function will be used by KVM to distinguish MMIO pfns and give them UC memory type in the EPT page tables (on Intel processors, EPT memory types work like MTRRs).
