kernel: kvm: reporting emulation failures to userspace

It was found that reporting emulation failures to user space could lead to either a local CVE-2014-7842 or a L2-L1 CVE-2010-5313 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain...
