2017-11-16 Thread Vikas C Sajjan
The platforms which support only IOAPIC mode, pass the SCI information above the legacy space (0-15) via the FADT mechanism and not via MADT. In such cases the mp_override_legacy_irq() used by acpi_sci_ioapic_setup() to register SCI interrupts fails for interrupts >= 16, since it is meant to
