From 54c9b2253d34e8998e4bff9ac2d7a3ba0b861d52 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Mon, 4 Mar 2013 19:45:52 +0000 Subject: powerpc: Set DSCR bit in FSCR setup We support DSCR (Data Stream Control Register) so we should make sure we set it in the FSCR (Facility Status & Control Register) incase some firmwares don't set it. If we don't set this, we'll take a facility unavailable exception when using the DSCR.
