Summary

main.c manages the kexec segments. Due to our inability to overcommit,
we need to know how much memory is available. commit_limit is the grand
total allowed. committed_as is the current memory used. mem_avail is
what Linux tells us is available. Find these from /proc/meminfo. We'll
use them later to allocate the biggest possible segment sizes, but for
now print the raw numbers.
