Ryan,

See Shawn's "[PATCH 00/17] arch/arm/mach-* late_initcall cleanup".

I haven't looked closely at this yet. I think there may be some platforms
where the late_initcall's might cause a problem when making an ARM
unified kernel.

Actually I have a question about the ARM unified kernel.

Wouldn't every mach-* supported by a unified kernel have to at least
be the same ARM variant (i.e. they share a common compiler setup)?
The ep93xx is an arm920t. Are there any other mach-* types that use
that?

Regards,
Hartley
