Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Revert r243960 based on feedback regarding keeping x86 headers unified
(mdf@, tijl@) and use of KASSERT/systm.h in bus.h (zeising@, bde@). Alternate implementation will be made in a separate commit.
