It would, and I hoped the spec would clarify that, but I didn't see anything. If there's a reason to have acpi_atomic_read() work differently than acpi_read() in this respect, that's fine. I just don't see it yet. If they *can* be made similar in this, I think we might be able to collapse them into a single, smaller implementation. > On the other hand I would expect hardware that really requires 64bit > to be rare because 32bit OS would always have some trouble with > it. -- 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
