Why does arch/x86/kernel/acpi/sleep.c::x86_acpi_suspend_lowlevel()

Would it not be CPU#0 that comes back up, and should it not get
per_cpu_offset(0) ?
Wanna me try `initial_gs = per_cpu_offset(0);` too?
Hm, yes please. There's another one to make zero on the next line up, I
think?
So,
```
early_gdt_descr.address = (unsigned long)get_cpu_gdt_rw(0);
initial_gs = per_cpu_offset(0);
```
?
Should I leave `smpboot_control = 0;` commented out, or I should
uncomment it back?
