    x86: make ioremap() UC by default · 9af993a9

    Yes! A mere 120 c_p_a() fixing and rewriting patches later,
    we are now confident that we can enable UC by default for
    ioremap(), on x86 too.
    
    Every other architectures was doing this already. Doing so
    makes Linux more robust against MTRR mixups (which might go
    unnoticed if BIOS writers test other OSs only - where PAT
    might override bad MTRRs defaults).
