Author: jhb Date: Fri Sep 30 00:31:17 2016 New Revision: 306466 URL: https://svnweb.freebsd.org/changeset/base/306466 Log: MFC 303886: Add additional constants. - Add constants for the fields in the root-entry table address register, namely the root type type (RTT) and root table address (RTA) mask. - Add macros for the bitmask of the domain ID field in the second word of context table entries as well as a helper macro (DMAR_CTX2_GET_DID) to extract the domain ID from a context table entry.
