-IASL/RHCT: Enable dumping and compiling newly added nodes. The RHCT table is updated with new nodes. Add compile and dump functionality for these new structures.
-
-AcpiExec: Added a new command, ?interrupt?. The Interrupt command simulates an interrupt with a IntID (GSIV) equal to the first argument of the call/invocation. The acpiexec code simulates the behavior by OSPM: execute the _EVT method of the GED device associated with that IntID. Submitted by: Jose Marinho jose.marinho@arm.com.

-AcpiExec: Detect GED device and keep track of _EVT. The GED device is described by a _HID of ACPI0013. This code traverses the namespace identifying all GED devices. For each GED device in the namespace we record the Interrupt object and the _EVT method. This information is used when an interrupt is simulated via the ?interrupt? command.
