Pull ACPI updates from Rafael Wysocki:
"These are ACPICA updates including ACPI 6.3 support among other
things, APEI updates including the ARM Software Delegated Exception
Interface (SDEI) support, ACPI EC driver fixes and cleanups and other
assorted improvements.
Specifics:
- Update the ACPICA code in the kernel to upstream revision 20190215
including ACPI 6.3 support and more:
* New predefined methods: _NBS, _NCH, _NIC, _NIH, and _NIG (Erik
Schmauss).
* Update of the PCC Identifier structure in PDTT (Erik Schmauss).
* Support for new Generic Affinity Structure subtable in SRAT
(Erik Schmauss).
* New PCC operation region support (Erik Schmauss).
* Support for GICC statistical profiling for MADT (Erik Schmauss).
* New Error Disconnect Recover notification support (Erik
Schmauss).
* New PPTT Processor Structure Flags fields support (Erik
Schmauss).
* ACPI 6.3 HMAT updates (Erik Schmauss).
* GTDT Revision 3 support (Erik Schmauss).
* Legacy module-level code (MLC) support removal (Erik Schmauss).
* Update/clarification of messages for control method failures
(Bob Moore).
* Warning on creation of a zero-length opregion (Bob Moore).
* acpiexec option to dump extra info for memory leaks (Bob Moore).
* More ACPI error to firmware error conversions (Bob Moore).
* Debugger fix (Bob Moore).
* Copyrights update (Bob Moore)
