   4  * The variables and functions in this file are used by the procentry/
   5  * procentry syslib functions when linked with userspace processes. For
   6  * kernel processes, the same variables and function are defined
   7  * elsewhere. This enables different functionality and variable sizes,
   8  * which is needed is a few cases.
