Description

The xhat infrastructure was added to support hardware such as the zulu graphics card - hardware which had on-board MMUs. The VM used the xhat code to keep the CPU's and Zulu's page tables in-sync. Since the only xhat user was zulu (which is gone), we can safely remove it simplifying the whole VM subsystem.

Note to reviewers: AS_BUSY flag was used solely by xhat
