CVS commit: src/sys/kern

[Matt Thomas]

Module Name:    src
Committed By:   matt
Date:           Tue Jan  4 01:40:19 UTC 2011

Modified Files:
        src/sys/kern: kern_ksyms.c

Log Message:
When determining max/min sym value, ignore ABS symbols which don't
have a type.  This stops ksym thinking that the _KERNEL_OPT symbols
could actually be useful.
