Here we go...

# ls /proc/ppc64/rtas
.   clock      frequency  progress    rtasmsgs  volume
..  error_log  poweron    rmo_buffer  sensors

With the addition of rmo_buffer you can make rtas calls from user space.
  Thus we may be able to get rid of the following items.

o clock - get/set platform time.
o frequency - set the frequency of the system speaker.
o progress - read/write data to the system led display
o volume - set the volume of the system speaker.
o power_on - set a future poweron time for the system

The remaining should be retained

o rtasmsgs - turn on/off rtas event messages to /var/log/message.
o error_log - rtas_errd uses this to get rtas events from the kernel.
o rmo_buffer - get a rmo region to make rtas calls from user space.
o sensors - displays the surrent state of system sensors

All of theses are defined in arch/ppc64/kernel/rtas-proc.c, except for
error_log which is in arch/ppc64/kernel/rtasd.c if anyone cares to look.
