- * * Applied fixes from Bruce Evans to fix COW bugs, >1MB kernel loading,
- *   profiling, and various protection checks that cause security holes
- *   and system crashes.
- * * Changed min/max/bcmp/ffs/strlen to be static inline functions
- *   - included from cpufunc.h in via systm.h. This change
- *   improves performance in many parts of the kernel - up to 5% in the
- *   networking layer alone. Note that this requires systm.h to be included
- *   in any file that uses these functions otherwise it won't be able to
- *   find them during the load.
- * * Fixed incorrect call to splx() in if_is.c
- * * Fixed bogus variable assignment to splx() in if_ed.c
