Subject: [PATCH] [BZ 192022] dbginfo: Added and removed commands
From: Mario Held <mario.held@de.ibm.com>

Description:   dbginfo.sh: Collect /proc/kallsyms, issue additional commands
Symptom:       - Required data gets not collected during run of dbginfo.sh  
               - vmcp q cache command always fails
Problem:       - some commands yet missing in dbginfo.sh script
               - command vmcp q cache is missing a mandatory parameter
Solution:      Stop to issue a vmcp q cache command (fails always) and add 
               - collect /proc/kallsyms as a tgz file (because of huge size)
               - lscpu -ye
               - vmcp q memassist
               - vmcp q pcifunction
               - vmcp q vmrelocate
Reproduction:  Run the dbginfo.sh and check for results in DBGINFOxxx.tgz file 
               - /proc/kallsyms
               - zvm_runtime.out
               - runtime.out
