help
Enabling this option allows for the removal of memory (RAM)
from the kernel mappings to be used for hardware tracing.

help
This enables support for IBM Virtual Accelerator Switchboard (VAS).
VAS allows accelerators in co-processors like NX-GZIP and NX-842
to be accessible to kernel subsystems and user processes.
VAS adapters are found in POWER9 based systems.
If unsure, say N.
