  v1.28

    19990201   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

	       Extended the driver to be able to use Cyrix style ARRs.

    19990204   Richard Gooch <rgooch@atnf.csiro.au>

	       Restructured Cyrix support.

  v1.29

    19990204   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

	       Refined ARR support: enable MAPEN in set_mtrr_prepare()

	       and disable MAPEN in set_mtrr_done().

    19990205   Richard Gooch <rgooch@atnf.csiro.au>

	       Minor cleanups.

  v1.30

    19990208   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

               Protect plain 6x86s (and other processors without the

               Page Global Enable feature) against accessing CR4 in

               set_mtrr_prepare() and set_mtrr_done().

    19990210   Richard Gooch <rgooch@atnf.csiro.au>

	       Turned <set_mtrr_up> and <get_mtrr> into function pointers.

  v1.31

    19990212   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

               Major rewrite of cyrix_arr_init(): do not touch ARRs,

               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   Zoltn Bszrmnyi <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   Zoltn Bszrmnyi <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   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

               Remove Cyrix "coma bug" workaround from here.

               Moved to linux/arch/i386/kernel/setup.c and

               linux/include/asm-i386/bugs.h

    19990228   Richard Gooch <rgooch@atnf.csiro.au>

	       Added MTRRIOC_KILL_ENTRY ioctl(2)

	       Trap for counter underflow in <mtrr_file_del>.

	       Trap for 4 MiB aligned regions for PPro, stepping <= 7.

    19990301   Richard Gooch <rgooch@atnf.csiro.au>

	       Created <get_free_region> hook.

    19990305   Richard Gooch <rgooch@atnf.csiro.au>

	       Temporarily disable AMD support now MTRR capability flag is set.

  v1.32

    19990308   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

	       Adjust my changes (19990212-19990218) to Richard Gooch's

	       latest changes. (19990228-19990305)

  v1.33

    19990309   Richard Gooch <rgooch@atnf.csiro.au>

	       Fixed typo in <printk> message.

    19990310   Richard Gooch <rgooch@atnf.csiro.au>

	       Support K6-II/III based on Alan Cox's <alan@redhat.com> patches.

  v1.34

    19990511   Bart Hartgers <bart@etpmod.phys.tue.nl>

	       Support Centaur C6 MCR's.

    19990512   Richard Gooch <rgooch@atnf.csiro.au>

	       Minor cleanups.

  v1.35

    19990707   Zoltn Bszrmnyi <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   Zoltn Bszrmnyi <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   Zoltn Bszrmnyi <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   Zoltn Bszrmnyi <zboszor@mail.externet.hu>

	       Double check for Intel in mtrr_add()'s big switch() because

	       that revision check is only valid for Intel CPUs.

    19990819   Alan Cox <alan@redhat.com>

               Tested Zoltan's changes on a pre production Athlon - 100%

               success.

    19991008   Manfred Spraul <manfreds@colorfullife.com>

    	       replaced spin_lock_reschedule() with a normal semaphore.

  v1.36

    20000221   Richard Gooch <rgooch@atnf.csiro.au>

               Compile fix if procfs and devfs not enabled.

	       Formatting changes.

  v1.37

    20001109   H. Peter Anvin <hpa@zytor.com>

	       Use the new centralized CPU feature detects.



  v1.38

    20010309   Dave Jones <davej@suse.de>

	       Add support for Cyrix III.



  v1.39

    20010312   Dave Jones <davej@suse.de>

               Ugh, I broke AMD support.

	       Reworked fix by Troels Walsted Hansen <troels@thule.no>



  v1.40

    20010327   Dave Jones <davej@suse.de>

	       Adapted Cyrix III support to include VIA C3.



  v2.0

    20020306   Patrick Mochel <mochel@osdl.org>

               Split mtrr.c -> mtrr/*.c

               Converted to Linux Kernel Coding Style

               Fixed several minor nits in form

               Moved some SMP-only functions out, so they can be used

                for power management in the future.

               TODO: Fix user interface cruft.
