This patch is the response to changes in <pids> types.
These additional modifications were also incorporated.
. ps -------------------------------------------------
pr_wname was eliminated as it just duplicated pr_wchan
pr_wchan referenced WCHAN_ADDR in error, vs WCHAN_NAME
pr_nwchan referenced WCHAN_NAME, not proper WCHAN_ADDR
