That's because the fsl-mc driver selects GENERIC_MSI_IRQ_DOMAIN and not
all arches implement the support for the option. I can submit a patch
that adds explicit dependencies on arches that it was build-tested (x86,
arm, powerpc, all both 32 and 64 bits) similar to how it's done here
[1]. Let me know if you're ok with this fix and i'll submit the fix to
staging.    

Ugh, you should not be selecting that option, but rather depending on
the option, right?    

All users in the kernel use "select", so i don't think so. An 
interesting use that adds explicit dependencies on architectures can be
seen here [1], in the generic code. I've proposed a patch [2] that does 
a similar thing for mc-bus. I think it's a good approach as it keeps 
things under control by explicitly specifying the architectures on which
the driver was compile-tested.

Any resolution of this?

Ping?

I have a patch in my queue, somewhere, that should resolve this, I
think.  I have 600+ staging patches in my todo queue right now, that's
what I get for trying to have a vacation...

I'll get to it soon, it's not lost, thanks.
