Subject: [PATCH 0/2]intel-iommu: reserve IOMMU register space

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...
