Subject: Re: [PATCH 23/73] sparc: don't use module_init in non-modular
 pci.c code

> The pci.o is built for SPARC64_PCI -- which is bool, and hence
> this code is either present or absent.  It will never be modular,
> so using module_init as an alias for __initcall can be somewhat
> misleading.
> 
> Fix this up now, so that we can relocate module_init from
> init.h into module.h in the future.  If we don't do this, we'd
> have to add module.h to obviously non-modular code, and that
> would be a worse thing.

> Note that direct use of __initcall is discouraged, vs. one
> of the priority categorized subgroups.  As __initcall gets
> mapped onto device_initcall, our use of device_initcall
> directly in this change means that the runtime impact is
> zero -- it will remain at level 6 in initcall ordering.
