vtophys() was checking for out-of-range addresses incorrectly: vfn_2mb
is already shifted to account for 2 MB hugepages, but it was being
compared with a mask that did not account for the shift. This would
allow out-of-bounds access to the 128tb map array for certain invalid
addresses (it had no effect on addresses within the valid userspace
range).

Also add a space between Copyright and (c).
The copyright year can be determined using git metadata.
Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.
Performed using this command:
git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

This helps weed out functions that should be static, functions that are
not declared in public header files, and .c files that don't include
their .h interface headers.

The Linux pagemap-based implementation obviously does not
work on FreeBSD. DPDK has data structures describing the huge
pages it has allocated, so use that instead when we need to
populate new 2MB mappings in our tables.
