    kernel - Warn/assert on broken ACPI MADT
    
    * Add warnings and assertions for broken ACPI MADT tables.  I encountered
      this trying to boot a 3990X on a motherboard with an old BIOS that didn't
      support it.  It tried to boot anyway, but the MADT table was mangled
      and caused a null-pointer indirection in the kernel.  Assert nicely
      instead.
