  • The old code allowed very strange memory types. Now it works like
    all the other video drivers: ioremap_wc is used unconditionally,
    and MTRRs are set if PAT is unavailable (unless MTRR is disabled
    by a module parameter).

    UC, WB, and WT support is gone. If there are MTRR conflicts that prevent
    addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's
    better to just turn off MTRR support entirely.

    As an added bonus, any MTRR added is freed on unload.
