     * Enabling application processors is done late in the boot process for
     * two reasons :
     *  - It's much simpler to bootstrap with interrupts disabled on all
     *    processors, enabling them only when necessary on the BSP.
     *  - Depending on the architecture, the pmap module could create per
     *    processor page tables. Once done, keeping the kernel page tables
     *    synchronized requires interrupts (and potentially scheduling)
     *    enabled on all processors.
     *
     * Anything done after this call and before running the scheduler must
     * not alter physical mappings.
