-          The 68060 generally uses copyback caching of recently accessed data.

-          here will force supervisor (kernel) accesses to use writethrough

-          straight away, so that cache and memory data always agree.
-          Writethrough caching is less efficient, but is needed for some

+          The 68060 generally uses copyback caching of recently accessed data.

- * INET         An implementation of the TCP/IP protocol suite for the LINUX
- *              operating system.  INET is implemented using the  BSD Socket
- *              interface as the means of communication with the user level.
- *
- *              IP/TCP/UDP checksumming routines
- *
- * Authors:     Jorge Cwik, <jorge@laser.satlink.net>
- *              Arnt Gulbrandsen, <agulbra@nvg.unit.no>
- *              Tom May, <ftom@netcom.com>
- *              Andreas Schwab, <schwab@issan.informatik.uni-dortmund.de>
- *              Lots of code moved from tcp.c and ip.c; see those files
- *              for more names.

- * 03/02/96     Jes Sorensen, Andreas Schwab, Roman Hodek:
- *              Fixed some nasty bugs, causing some horrible crashes.
- *              A: At some points, the sum (%0) was used as
- *              length-counter instead of the length counter
- *              (%1). Thanks to Roman Hodek for pointing this out.
- *              B: GCC seems to mess up if one uses too many
- *              data-registers to hold input values and one tries to
- *              specify d0 and d1 as scratch registers. Letting gcc
- *              choose these registers itself solves the problem.

- * 1998/8/31    Andreas Schwab:
- *              Zero out rest of buffer on exception in

+ * INET         An implementation of the TCP/IP protocol suite for the LINUX
+ *              operating system.  INET is implemented using the  BSD Socket
+ *              interface as the means of communication with the user level.
+ *
+ *              IP/TCP/UDP checksumming routines
+ *
+ * Authors:     Jorge Cwik, <jorge@laser.satlink.net>
+ *              Arnt Gulbrandsen, <agulbra@nvg.unit.no>

+ *              Andreas Schwab, <schwab@issan.informatik.uni-dortmund.de>
+ *              Lots of code moved from tcp.c and ip.c; see those files
+ *              for more names.

+ * 03/02/96     Jes Sorensen, Andreas Schwab, Roman Hodek:
+ *              Fixed some nasty bugs, causing some horrible crashes.
+ *              A: At some points, the sum (%0) was used as
+ *              length-counter instead of the length counter
+ *              (%1). Thanks to Roman Hodek for pointing this out.
+ *              B: GCC seems to mess up if one uses too many
+ *              data-registers to hold input values and one tries to
+ *              specify d0 and d1 as scratch registers. Letting gcc
+ *              choose these registers itself solves the problem.
