This patchset introduces KVM per VM exit statistics monitoring via debugfs, as well as moves a tool to display VM statistics from qemu to tools/. The new debugfs per VM statistics are an alternative to the already available VM tracepoints. They are easier to read and have low overhead. The kvm_stat python script is moved to the kernel, as we can make sure here that the right version of the script is used with the right kernel version. This is not given for qemu, as it supports a wide range of linux kernel versions.
