This is on top of the parallel boot v10 series.
Remove the global variables initial_gs, initial_stack, and early_gdt_descr from the 64-bit boot code. The stack, GDT, and GSBASE can be determined from the CPU number.
Brian Gerst (6): x86/smpboot: Use CPU number instead of APIC ID for single CPU startup x86/smpboot: Use current_task to get idle thread x86/smpboot: Remove initial_stack on 64-bit x86/smpbppt: Remove early_gdt_descr on 64-bit x86/smpboot: Remove initial_gs x86/smpboot: Simplify boot CPU setup
