From e32edf4fd0fa4897e12ca66118ab67bf257e16e4 Mon Sep 17 00:00:00 2001 From: Nikolay Nikolaev Date: Thu, 26 Mar 2015 14:39:28 +0000 Subject: KVM: Redesign kvm_io_bus_ API to pass VCPU structure to the callbacks. This is needed in e.g. ARM vGIC emulation, where the MMIO handling depends on the VCPU that does the access.
