Symptoms:
	PHCO_22921:
	Repackage base HP-UX patch PHCO_22686 to VVOS:

	Based on HP-UX patch PHCO_22686:
	top(1) output functionality corrected.

	Based on HP-UX patch PHCO_21892:
	In a multi processor system, if any processor other
	than the last processor is deallocated, top(1) shows
	incorrect cpu usage, average cpu usage and load averages
	information.

	PHCO_19496:
	Repackage base HP-UX patch PHCO_17439 for VVOS.

	Based on HP-UX patch PHCO_17439:
	1. Long tty names cause unaligned output for top(1).

	2. top(1) reports wrong tty name for processes which
	are not attached to a terminal.

	3. top(1) may dump core if certain undocumented
	behaviour of qsort(3) changes in future releases.

	Based on HP-UX patch PHCO_14809:
	top(1) displays wrong usernames.
	Extra character in top output at the lower right
	corner of the screen.  Floating exception when
	screen is small.
	top(1) does not display any processes on a small
	screen for a multi processor system which has
	a large number of CPUs

Defect Description:
	PHCO_22921:
	Repackage base HP-UX patch PHCO_22686 to VVOS:

	Based on HP-UX patch PHCO_22686:
	top(1) output functionality corrected.

	Resolution:
	Code has been modified to take care of this issue.
	The allocation of processors on fly also has been
	taken care.

	Based on HP-UX patch PHCO_21892:
	In a multiprocessor system of say, n processors,
	when a processor other than processor "n" is
	deallocated, top(1) skips the information of
	processor "n" instead of the deallocated processor.
	While calculating the averages, top(1) takes the
	deallocated processor into consideration instead
	of processor "n".

	Resolution:
	The mpctl(2) call is used in top(1) to find the
	allocated processors' numbers and top(1)
	is made to display and calculate information
	only for the allocated processors.

	PHCO_19496:
	Repackage base HP-UX patch PHCO_17439 for VVOS.

	Based on HP-UX patch PHCO_17439:
	1. If the tty name of a process is more than 6 characters,
	   the line corresponding to that process in the top output
	   appears to be shifted towards right.  This results in
	   poor legibility.

	Resolution:
	    top(1) will align the process information and the header
	    dynamically based on the length of the longest tty name.

	2. top(1) reports 'rroot' as tty name for processes which
	   are not attached to a terminal. The reason is, a process,
	   which is not attached to a terminal, will have the fields
	   pst_major and pst_minor of the process data structure
	   equal to -1 which matches the major and minor numbers
	   of the boot device /dev/rroot.

	Resolution:
	   If the pst_major and pst_minor fields of the process
	   data structure are equal to -1, top(1) will display '?'
	   indicating that the process is not attached to a
	   terminal.

	3. top(1) may dump core if certain undocumented behaviour
	   of qsort(3) changes in future releases.

	Resolution:
	   top(1) has been modified so that it does not rely
	   on the undocumented behaviour of qsort(3)

	Based on HP-UX PHCO_14809:
	top(1) displays wrong usernames due to collisions
	while hashing.
	Extra character in top output at the lower right
	corner of the screen.
	Floating exception when screen is small. This occurs
	when the number of processes which can be displayed on
	the screen becomes zero.
	top(1) does not display any processes on a small screen
	for a multi processor system which has a large number of
	CPUs. The individual CPU state information dominates the
	screen and there is no space left for displaying processes.
