Problem Description: 

4159925: "UEx000 167Mhz512kb CPU - passed POST/SunVTS, but failed
        compress/uncompress test" This patch augments the existing
        SunVTS test suite with cpudatatest in order to detect CPU's
        which may pass other tests and yet fail a
        compress/uncompress sequence.

4183870: "The svrmgr1 command of ORACLE8 dumps core under bad cpu module."
	 This patch augments the existing SunVTS test suite with
	 cpudatatest in order to detect CPU's which may exhibit the same
	failure mode.

Special Notes
-------------
1) See cpudatatest.txt for a description of command line usage and ERROR messages.

2) "cpudatatest" representation on the status panel of SunVTS OpenLook screen
   is too long so one or two characters may overlap with "Passes" labels.

3) The user should not attempt to change the Processor Affinity for
   any instance of cpudatatest because the test is designed to run with
   the defaults assigned during probing.

4) The following bugs have been filed in connection with this patch:

	Bug Id: 4240007 - UI (CDE/OL/TTY) would vanish if user attempt 
			to alter "cpudatatest"

	Bug Id: 4240072 - vtstty (TTY User Interface) would produce a 
			core with entry to "cpudatest"

	The simplest workaround is to restart the UI if it should vanish
	and then run cpudatatest with the default parameters. In all cases 
	running cpudatatest with the default parameter values works as 
	expected. The problem has only been observed when the user has 
	attempted to change cpudatatest's parameters from the UI.
