On some platforms such as that based on x86, ia64 etc, root bus is

On these platforms, the patch series "PCI: get DMA configuration from
parent device" when applied causes kernel crash. So add a check for this
in of_pci_dma_configure()

Wouldn't these arches have OF disabled and call an empty function?
Regardless, we still need this.

It might be an idea to read the subject line...

"fix BUG: unable to handle kernel"
Russell,

I will fix the subject as "fix BUG: unable to handle kernel NULL pointer" and re-send.

Thanks

Murali

which is meaningless. It needs a much better subject line before it can
be committed.
