    SubjectPage Attribute Table (PAT) support?
    The Page Attribute Table (PAT) is an extension to the x86 page table format
    that lets you enable Write Combining on a per-page basis. Details can be found
    in chapter 9.13 of the Intel Architecture Software Developer's Manual, Volume 3
    (System Programming).

    I noticed that 2.4 doesn't support the Page Attribute Table, despite the fact
    that it has a X86_FEATURE_PAT macro in processor.h. Are there any plans to add
    this support? Ideally, I'd like it to be as a parameter for ioremap.
