Support 2TB phys mem

This change expands the direct map to 4 slots (512GB each), to support
machines with up to 2TB physical memory. Should further expansion be
required, this change provides the means to do that with a single #define
change.

Ingo Schwarze -mandoc Better documentation – on the web and for LibreSSL video is now published

Contributed by Tom Smyth on from the buns-and-caffeine dept.

Tom Smyth has another article (and video) for us:

Ingo Schwarze (schwarze@) delivered a great talk on documentation in EuroBSDCon 2018. Ingo's slides have been on-line since September at OpenBSD events.html under the EuroBSD Con 2018. Anyone who follows the mailing lists would see Ingo's consistent attention to detail. In this talk Ingo interestingly points out that application of consistent attention to detail in documentation, also improves the quality of the software that is being documented. Ingo shows that if a program is difficult to document, then it is likely due to serious flaws in the program's design.
