The series improves handling of invalid IRQs in ACPI glue layer along with
preventing setup SCI on HW reduced platforms as it prescribed by the spec.

Patch 1 is just convenient to add to the series.

Patches 2 and 3 make consistent value and variable types for SCI and GSI in
ACPI code.

Patch 4 prevents setting up SCI on HW reduced platforms.

The series has been tested on T100TA (HW reduced platform) and
on Intel Kabylake.

In v4:
- drop upstreamed patches
- drop patch which belongs to other (future) series
- rework approach to address Rafael's comment

Andy Shevchenko (4):
  ACPI / boot: Swap variables in condition in acpi_register_gsi_ioapic()
  ACPI / boot: Get rid of ACPI_INVALID_GSI
  ACPI / boot: Use INVALID_ACPI_IRQ instead of 0 for
    acpi_sci_override_gsi
  ACPI / boot: Don't setup SCI on HW reduced platforms
