Description
Comparing the output of 'dtrace -l -P sysinfo' with the probes described in
table 23-1 of the sysinfo chapter reveals several probes that are undocumented:

canch
mdmint
outch
rawch
rcvint
xmtint

Plus the following which don't exist:

cpu_ticks_*
msg
sema
wait_ticks_io

The cpu_ticks_* are covered by a separate bug (6206973) because they include
a demo script shipped in /usr/demo/dtrace and are therefore a higher priority.

There are also some other kstats in the 'sys' class that don't have a 
corresponding sysinfo probe:

cpumigrate
crtime
intr
iowait
snaptime
syscall

Some of these are calculated dynamically at read time, and others are 
defunct.  It should be documented that not _all_ sys kstats have a
corresponding sysinfo probe.
