Re: [PATCH] dma: mv_xor_v2: new driver

Marc,

This doesn't seem to be an issue introduced by my patch itself, but
rather a problem with the MSI subsystem itself. Is this already a known
issue (possibly already fixed), or should I investigate?

Seems like something is selecting GENERIC_MSI_IRQ_DOMAIN on a system
that doesn't implement the required bits.

It may be that we need to implement something like
HAS_GENERIC_MSI_IRQ_DOMAIN, and make GENERIC_MSI_IRQ_DOMAIN conditional
on that. Or just whitelist the architectures that do implement this.

Any chance you could have a closer look?

Thanks,

	M.

Thanks!

Thomas
