 in turn, be used internally by the class to write to MSR's. In my example im simply forwarding the call to a predefined routine in vdm.hpp.

 Once you have a lambda defined like this you can go ahead and create a `vdm::msrexec_ctx`. The lambda you pass to `vdm::msrexec_ctx::exec` will be executed in ring-0. Please note that you should be very aware of what you are calling in this lambda as to not make any printfs, malloc's, std::vector::push_back, or anything that might syscall. Also note that the lambda you pass must be of type `std::function<void(void*, get_system_routine_t)>`.
