-               leave them as the BIOS have set them up.
-               Enable usage of all 8 ARRs.
-               Avoid multiplications by 3 everywhere and other
-               code clean ups/speed ups.
-    19990213   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Set up other Cyrix processors identical to the boot cpu.
-               Since Cyrix don't support Intel APIC, this is l'art pour l'art.
-               Weigh ARRs by size:
-               If size <= 32M is given, set up ARR# we were given.
-               If size >  32M is given, set up ARR7 only if it is free,
-               fail otherwise.
-    19990214   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Also check for size >= 256K if we are to set up ARR7,
-               mtrr_add() returns the value it gets from set_mtrr()
-    19990218   Zoltán Böszörményi <zboszor@mail.externet.hu>

-               linux/include/asm-i386/bugs.h

-               Support Centaur C6 MCR's.
-    19990512   Richard Gooch <rgooch@atnf.csiro.au>
-               Minor cleanups.
-  v1.35
-    19990707   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Check whether ARR3 is protected in cyrix_get_free_region()
-               and mtrr_del(). The code won't attempt to delete or change it
-               from now on if the BIOS protected ARR3. It silently skips ARR3
-               in cyrix_get_free_region() or returns with an error code from
-               mtrr_del().
-    19990711   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Reset some bits in the CCRs in cyrix_arr_init() to disable SMM
-               if ARR3 isn't protected. This is needed because if SMM is active
-               and ARR3 isn't protected then deleting and setting ARR3 again
-               may lock up the processor. With SMM entirely disabled, it does
-               not happen.
-    19990812   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Rearrange switch() statements so the driver accomodates to
-               the fact that the AMD Athlon handles its MTRRs the same way
-               as Intel does.
-    19990814   Zoltán Böszörményi <zboszor@mail.externet.hu>
-               Double check for Intel in mtrr_add()'s big switch() because
-               that revision check is only valid for Intel CPUs.
