The early mappings are temporary, but they are cached, for they use __pgprot(__PAGE_KERNEL_IO), which is (__PAGE_KERNEL | _PAGE_IOMAP) rather than __pgprot(__PAGE_KERNEL_IO_NOCACHE) or its variants. We just need to update the permanent mappings to match. cheers, Len Brown, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
