panic does not require a \n at the end. When one is provided, it looks wrong.

Some BIOS seem to provide memory regions <16M in their reserved memory
region reporting table. Since the extent only covered memory starting
at 16M, these regions could not be reserved and would in turn cause a
panic. Make the extent start at 0 and immediately reserve the first
16M right away, so that we can change the reserved memory allocator to
EX_CONFLICTOK to make allocations succeed if they are already reserved.

Adding IOMMU support for AMD Vi and Intel VTD (disabled)
This creates separate domains for each PCI device and can provide protection
against invalid memory access. Needed for Passthrough PCI from vmd.
