From cbe487fac7fc016dbabbcbe83f11384e1803a56d Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 3 Aug 2010 10:39:35 +0200 Subject: KVM: PPC: Add mtsrin PV code This is the guest side of the mtsr acceleration. Using this a guest can now call mtsrin with almost no overhead as long as it ensures that it only uses it with (MSR_IR|MSR_DR) == 0. Linux does that, so we're good.
