	  This enables support for IBM Virtual Accelerator Switchboard (VAS).

	  VAS devices are found in POWER9-based and later systems, they
	  provide access to accelerator coprocessors such as NX-GZIP and
	  NX-842. This config allows the kernel to use NX-842 accelerators,
	  and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
	  and POWER10 PowerVM platforms.

	  If unsure, say "N".
