Can you send us the content of /proc/cmdline?
$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-4.16.16-300.fc28.x86_64
root=/dev/mapper/luks-1d176bad-1b27-4e38-8c18-61a8b96517db ro

Also check any RAMdisks you may have (e.g. "df -h | grep
tmpfs"). See
if any of them are possibly eating up RAM. I'd suspect /tmp and
(possibly) your swap partition.
$ df -h |grep tmpfs
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs 3.9G 1.8M 3.9G 1% /run
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
tmpfs 3.9G 104K 3.9G 1% /tmp
tmpfs 789M 16K 789M 1% /run/user/42
tmpfs 789M 24K 789M 1% /run/user/1000
so this still would leave something like 40GB missing.
I opened up a bug on the kernel tracker at
https://bugzilla.redhat.com/show_bug.cgi?id=1593878
