I have sent this patch before to lkml, but it appears it wasn't picked up. Also
I have to admit this isn't tested. This is a patch against linus' tree.
ACPI_MADT_ENABLED is defined 1 (include/acpi/actbl1.h 501)
lapic_flags: an u32 of struct acpi_madt_local_sapic (include/acpi/actbl1.h 467)
--
'!' has a higher priority than '&', so as was
this won't test the first bit, but rather evaluates to false for any non-zero
lsapic->lapic_flags.
