From a4700a26107241cc7b9ac8528b2c6714ff99983d Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Sat, 20 May 2017 14:29:49 +1000 Subject: powerpc: Add PPC_FEATURE userspace bits for SCV and DARN instructions Providing "scv" support to userspace requires kernel support, so it must be advertised as independently to the base ISA 3 instruction set. The darn instruction relies on firmware enablement, so it has been decided to split this out from the core ISA 3 feature as well.
