Bjorn Helgaas 28eda5b8b4 [IA64] add driver for ACPI methods to call native firmware ... This driver for HPQ5001 devices installs a global ACPI OpRegion handler. AML methods can use this OpRegion to call native firmware entry points. ACPI does not define a mechanism for AML methods to call native firmware interfaces such as PAL or SAL. This OpRegion handler adds such a mechanism. After the handler is installed, an AML method can call native firmware by storing the arguments and firmware entry point to specific offsets in the OpRegion. When AML reads the "return value" offset from the OpRegion, this handler loads up the arguments, makes the firmware call, and returns the result.
