[PATCH] kdump: Fix for machine checkstop on DMA fault

[Haren Myneni]

Paul, If you are OK with this fix, please send it upstream.

Thanks
Haren

- Some machines checkstop on dma protection fault for ongoing DMA left 
in the first kernel. Since, we do not shutdown devices before the kdump 
boot, let them continue DMA to old kernel space.
