Subject: [PATCH v4 0/4] ACPI / boot: Don't handle SCI on HW reduced platforms

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
