Mark the read-only VMX and SVM module params, and a few other global variables, read-only after init. In many cases, KVM is royally hosed if a configuration knob changes while VMs are running, e.g. toggling the TDP knob would result in spectacular fireworks. This series is probably best queued very early in a cycle, as the result of mis-labeled variable is an unexpected kernel #PF.
