That seems optimistic.

I have no expectation that the majority of system vendors run the test suite, but I have every expectation that every system vendor runs Windows. We should behave as close to the tested mechanism as possible, ie do what Windows does - and that includes calling SetVirtualAddressMap(). -- Matthew Garrett | mj...@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
