    sys/i386/i386        db_interface.c machdep.c mp_machdep.c

    sys/i386/include     smp.h smptests.h 
  Log:
  New i386 SMP code:
  
  - The MP code no longer knows anything specific about an MP Table.
    Instead, the local APIC code adds CPUs via the cpu_add() function when
    a local APIC is enumerated by an APIC enumerator.
  - Don't divide the argument to mp_bootaddress() by 1024 just so that we
    can turn around and mulitply it by 1024 again.
  - We no longer panic if SMP is enabled but we are booted on a UP machine.
  - init_secondary(), the asm code between init_secondary() and ap_init()
    in mpboot.s and ap_init() have all been merged together in C into
    init_secondary().
  - We now use the cpuid feature bits to determine if we should enable
    PSE, PGE, or VME on each AP.
  - Due to the change in the implementation of critical sections, acquire
    the SMP TLB mutex around a slightly larger chunk of code for TLB
    shootdowns.
  - Remove some of the debug code from the original SMP implementation
    that is no longer used or no longer applies to the new APIC code.
  - Use a temporary hack to disable the ACPI module until the SMP code has
    been further reorganized to allow ACPI to work as a module again.
  - Add a DDB command to dump the interesting contents of the IDT.
