[Users] arcconf64: deprecated find_task_by_pid function is used. in IBM aacraid driver

[Aleksandar Ivanisevic]

This is from the latest IBM xSeries aacraid driver I had to apply 
because I was hit by a critical bug. Should I be worried?

arcconf64: deprecated find_task_by_pid function is used. If it is called 
by the proprietary ATI video driver it is ok, otherwise please report 
the case to users at openvz.org
