PNPACPI: truncate _CRS windows with _LEN > _MAX - _MIN + 1
The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that violate this. We experimentally determined that Windows truncates the resource so it doesn't extend past _MAX, so let's do the same thing in Linux. http://bugzilla.kernel.org/show_bug.cgi?id=15480 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: Rafael J.
