Reserve the memory space that Intel IOMMUs use so they aren't dynamically allocated by hot-plug operations. Seem on some systems when BIOS doesn't place IOMMU registers in a safe, non-hotplug location. ... until BIOS quickly changed.
Since modifying dmar.c, and information prints in the code, cleanup the info/warning prints in the first patch to use more std pr_*() functions and formatting. Second patch is core of the iomem space reservation. Bjorn had posted a similar patch a couple weeks back, and I informed him in a side note I had this patch set in my queue, just needed couple minor edits to complete. So, if you are having deja-vu, now you know why...
