... and this starts getting silly with the number of parens.

	return gicc->flags & ACPI_MADT_ENABLED ||
	       gicc->flags & ACPI_MADT_GICC_CPU_CAPABLE;

is entirely sufficient. Also:

	return gicc->flags & (ACPI_MADT_ENABLED | ACPI_MADT_GICC_CPU_CAPABLE);

also works.


vote for the second one, which is: gicc->flags & (ACPI_MADT_ENABLED | ACPI_MADT_GICC_CPU_CAPABLE)

Thanks,
