Routine Description:
This routine is called from the kernel initialization routine during
bootstrap to initialize the executive and all of its subcomponents.
Each subcomponent is potentially called twice to perform Phase 0, and
then Phase 1 initialization. During Phase 0 initialization, the only
activity that may be performed is the initialization of subcomponent
specific data. Phase 0 initialization is performed in the context of
the kernel start up routine with interrupts disabled. During Phase 1
initialization, the system is fully operational and subcomponents may
do any initialization that is necessary.
Arguments:
Number - Supplies the processor number currently initializing.
LoaderBlock - Supplies a pointer to a loader parameter block.
Return Value:
None.
