1) ACPICA kernel-resident subsystem:

Event Manager: History: Commit 18996f2db918 ("ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume") was added earlier to stop clearing of event status bits unconditionally on suspend and resume paths. Though this change fixed an issue on suspend path, it introduced regressions on several resume paths. In the case of S0ix, events are enabled as part of device suspend path. If status bits for the events are set when they are enabled, it could result in premature wake from S0ix. If status is cleared for any event that is being enabled so that any stale events are cleared out. In case of S0ix, events are enabled as part of device suspend path. If status bits for the events are set when they are enabled, it could result in premature wake from S0ix.

This change ensures that status is cleared for any event that is being enabled so that any stale events are cleared out.

2) iASL Compiler/Disassembler and ACPICA tools:

iASL: Implemented an enhanced multiple file compilation that combines named objects from all input files to a single namespace. With this feature, any unresolved external declarations as well as duplicate named object declarations can be detected during compilation rather than generating errors much later at runtime. The following commands are examples that utilize this feature:
iasl dsdt.asl ssdt.asl
iasl dsdt.asl ssdt1.asl ssdt2.asl
iasl dsdt.asl ssdt*.asl
