Idan Horowitz fd3be7ffcc Kernel: Setup APIC AP cores boot environment before init_stage2 ...

Since this range is mapped in already in the kernel page directory, we
can initialize it before jumping into the first kernel process which
lets us avoid mapping in the range into init_stage2's address space.

This brings us half-way to removing the shared bottom 2 MiB mapping in
every process, leaving only the Prekernel.
