/*
* debugfs ops for process ASIDs

*
* Provides a debugfs file that lists out the ASIDs currently associated
* with the processes.
*
* In the SH-5 case, if the DM.PC register is examined through the debug
* link, this shows ASID + PC. To make use of this, the PID->ASID
* relationship needs to be known. This is primarily for debugging.
