Description

It would be useful for the KPTI status and features in use to be reported in kernel messages rather than having to use mdb to determine whether it's enabled and then with or without PCID/INVPCID.

For example:

% dmesg | grep KPTI
Mar 18 17:22:42 omniosce unix: [ID 551322 kern.info] KPTI enabled (PCID in use, INVPCID not supported)
