Matthew Garrett 9340e1ccdf x86, ioapic, acpi quirk: disable IRQ 0 through I/O APIC for some HP systems
Some HP laptops have a problem with their DSDT reporting as
HP/SB400/10000, which includes some code which overrides all temperature
trip points to 16C if the INTIN2 input of the I/O APIC is enabled.  This
input is incorrectly designated the ISA IRQ 0 via an interrupt source
override even though it is wired to the output of the master 8259A and
INTIN0 is not connected at all.  So far two models have been identified,
namely nx6125 and nx6325.

Use a knob provided by the I/O APIC interrupt registration code to
abandon any attempts to route IRQ 0 through the I/O APIC for these
systems.
