From d69614a295aef72f8fb22da8e3ccf1a8f19a7ffc Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 18 Jun 2014 14:53:49 +0200 Subject: KVM: PPC: Separate loadstore emulation from priv emulation Today the instruction emulator can get called via 2 separate code paths. It can either be called by MMIO emulation detection code or by privileged instruction traps. This is bad, as both code paths prepare the environment differently. For MMIO emulation we already know the virtual address we faulted on, so instructions there don't have to actually fetch that information. Split out the two separate use cases into separate files.
