I renamed it prep_irq_for_enabled_exit().

And I realised that after patch 4, prep_irq_for_enabled_exit() has become a trivial function used 
only once.

So I swapped patches 1/2 with patches 3/4 and added a 5th one to squash prep_irq_for_enabled_exit() 
into its caller.

You didn't have any comment on patch 4 (that is now patch 2) ?

Thanks for the review
Christophe
