Re: linux-next: build failure in the staging tree (Was: kisskb: FAILED linux-next/s390-allmodconfig/s390x Mon Jul 31, 17:24)

Hi Stephen,

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.

---
Thanks & Best Regards, Laurentiu
