smp: Add --enable-ncpus option and fix build
* configfrag.ac (--enable-ncpus): Add option to set $mach_ncpus.
* i386/i386/cpu_number.h (CPU_NUMBER, cpu_number): New macros, set to 0 for
now.
* i386/i386/db_interface.c (cpu_interrupt_to_db): New function.
* i386/i386/db_interface.h (cpu_interrupt_to_db): New declaration.
* i386/i386/mp_desc.c (int_stack_base): New array.
(intel_startCPU): New function.
* i386/i386at/model_dep.c: Include <i386/smp.h>
(int_stack_top, int_stack_base): Turn into arrays
(i386at_init): Update accesses accordingly.
* i386/i386at/model_dep.h (int_stack_top, int_stack_base, ON_INT_STACK):
Likewise.
* i386/intel/pmap.c (cpus_active, cpus_idle, cpu_update_needed): Add
variables.
* i386/intel/pmap.h (cpus_active, cpus_idle, cpu_update_needed): Mark
extern.
* kern/cpu_number.h: Include <machine/cpu_number.h>
* linux/dev/arch/i386/kernel/irq.c (local_bh_count, local_irq_count):
Hardcode to the address of intr_count. We will not use the Linux code in
SMP mode anyway.
