[parisc-linux] init_idle and local_irq_save

[Grant Grundler <grundler@parisc-linux.org>]

Hi all,
I'm trying to get 2.6 SMP working on a UP box and was walking
through the init sequence. I have two questions related to init_idle()
in kernel/sched.c:

o local_irq_save()/local_irq_restore are called without an
  obvious local_irq_disable() call in between. Is this really
  needed for some other reason or is the local_irq_disable() missing?

o double_rq_lock() acquires the locks with lowest address first.
  double_rq_unlock() does not release those in the inverse order.
  Is that a problem?
  I'm just nervous since I didn't see the local_irq_disable()
  in init_idle() which would guarantee both unlock's happen atomically.

thanks,
grant
