* 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.
*
* It is highly recommended not to do anything else than starting the
* scheduler right after this call.
