arch/x86/kernel/smpboot.c: Clarify when irq processing begins.
Secondary cpus start with local interrupts disabled.
start_secondary() first initializes the new cpu, then it enables the
local interrupts. (although interrupts are enabled within smp_callin()
as well).
Right now, the local interrupts are enabled as a side effect of calling
ipi_call_lock_irq().
The attached patch clarifies when local interrupts are enabled.
