-Booting secondary processors
-----------------------------
-
-It's twisty and turny, so this is (roughly) the code path:
-
-start_of_day (i386/setup.c)
-smp_boot_cpus (i386/smpboot.c)
- * initialises boot CPU data
- * parses APIC tables
- * for each cpu:
- do_boot_cpu (i386/smpboot.c)
- * forks a new idle process
- * points initial stack inside new task struct
- * points initial EIP at a trampoline in very low memory
- * frobs remote APIC....
-
-On other processor:
- * trampoline sets GDT and IDT
- * jumps at main boot address with magic register value
- * after setting proper page and descriptor tables, jumps at...
- initialize_secondary (i386/smpboot.c)
- * simply reads ESP/EIP out of the (new) idle task
- * this causes a jump to...
- start_secondary (i386/smpboot.c)
- * reset all processor state
- * barrier, then write bitmasks to signal back to boot cpu
- * then barrel into...
- cpu_idle (i386/process.c)
