SubjectRe: [FIX] Compiler error on linux-2.4.11-pre4/arch/i386/kernel/mpparse.c
My fault. I'd tested this on SMP and Uniproc, but not uniproc with
IO apic support. Try hacking out the if CONFIG_SMP from this bit

#if CONFIG_SMP
# ifdef CONFIG_MULTIQUAD
# define TARGET_CPUS 0xf /* all CPUs in *THIS* quad */
# define INT_DELIVERY_MODE 0 /* physical delivery on LOCAL quad */
# else
# define TARGET_CPUS cpu_online_map
# define INT_DELIVERY_MODE 1 /* logical delivery broadcast to all procs */
# endif
#else
# define TARGET_CPUS 0x01
#endif

in smp.h. But you might run into something else. Now I understand which
combination breaks it, I'll do some testing and get you a patch ASAP.
