From ad0a048b096ac819f28667602285453468a8d8f9 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 24 Mar 2010 21:48:30 +0100 Subject: KVM: PPC: Add OSI hypercall interface MOL uses its own hypercall interface to call back into userspace when the guest wants to do something. So let's implement that as an exit reason, specify it with a CAP and only really use it when userspace wants us to. The only user of it so far is MOL.
