AFAIK Fedora uses the available RAM as a) buffer space, and b) the

BTW a slightly more user-friendly way to get that info is with the
free(1) command.
The joke is, the >60GB of missing memory doesn't even show up in free:
$ free
total used free shared buff/cache
available
Mem: 2400708 1093732 284844 121920 1022132 957848
Swap: 62499836 0 62499836
For some reason the kernel marks it as reserved.

Same goes for htop. It's showing I have 2.29G of memory.
Update: I upgraded from Fedora 27 to Fedora 28, and the same issue
persists. Of course, the kernel is almost the same.
This has to be some weird kernel / BIOS bug...
