Subject: [RESEND PATCH v1 0/2] Privileged process support on remote subsystem

Add support to run remote user process as privileged on remote
subsystem. The privileged user process can be given prioritized
access to remote processor resources. This is achieved in kernel
based on the group ID of the process. The kernel will have a
pre-defined fastrpc group ID and if the process's group ID matches
with it, then the process is treated as a privileged process. This
information is sent to the remote processor during PD initialization
and the PD is treated as a privileged PD.
