Thank you very much !

Apart from patch 1, patch 7 (and patch 16 that adds on top of it)
requires an ack from an ACPI core perspective. acpi_dma_configure()
should not affect x86/ia64 systems at all so those patches should
not really be controversial (patch 16 adds an IORT hook into
acpi_dma_configure() that is a nop by design on anything other than
ARM64), please let me know if they are ok.

Thank you again for your time,
Lorenzo
