Description

https://smartos.org/bugview/OS-6566

The KMDB unix module can trivially report the current %cr2 and %cr3 values. While the current %cr3 value will be of limited interest, especially post-KPTI where we can expect it to always be the failsafe value, it can't hurt, and at least provides the possibility of digging it out of the saved state at a later point.
