Summary: Radix on AIM, and all of Book-E (currently), can do direct addressing of user space, instead of needing to map user addresses into kernel space.

Test Plan: Tested on powerpcspe, powerpc64/booke, powerpc64/AIM Reviewed by: bdragon Differential Revision: https://reviews.freebsd.org/D25129 |
