What tree fails to compile?
grepping mainline:
./arch/x86/kernel/cpu/mcheck/mce_intel_64.c:asmlinkage void smp_thermal_interrupt(void) ./arch/x86/kernel/cpu/mcheck/p4.c:void smp_thermal_interrupt(struct pt_regs *regs) ./arch/x86/kernel/entry_64.S: apicinterrupt THERMAL_APIC_VECTOR,smp_thermal_interrupt ./arch/x86/kernel/traps_64.c:asmlinkage void __attribute__((weak)) smp_thermal_interrupt(void)
Notice the one in p4.c doesn't take void args.
I'll look into it.
