Ok the intel stuff has to boot the other CPU's in real mode (no I dont know
why intel did this either). We do a real mode start up in low memory using
the base of that CPU's kernel stack and jump into protected mode and to
the kernel entry code. the lock variable is used to detected 2nd or later
CPUs (bad things occur if CPU#2 also clears the BSS for example..)
