Log message:
Extend cmmu routines to return the caching mode to use for page tables.
Alter the 88200-specific code to enforce cache-inhibited page tables for
extremely old 88200 versions, and to disable write-back caching on systems
where xmem instructions do not behave correctly when applied to write-back
cached addresses.
No change introduced on 88110 systems, as well as most 88100 systems; the
affected systems are 88100 systems with 88100 revision < 10 and/or 88200
revision < 7; that is, only early MVME181 and MVME188 (not 188A) systems.
