From 4dea2d1a927c61114a168d4509b56329ea6effb7 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Mon, 28 Aug 2017 23:23:33 -0700 Subject: powerpc/powernv/vas: Define vas_init() and vas_exit() Implement vas_init() and vas_exit() functions for a new VAS module. This VAS module is essentially a library for other device drivers and kernel users of the NX coprocessors like NX-842 and NX-GZIP. In the future this will be extended to add support for user space to access the NX coprocessors. VAS is currently only supported with 64K page size.
