Hi, This is my first set of patches that works as I would expect, and the third revision I sent to mailing lists. Following up with my previous discussions about kernel rootkit mitigation via placing R/O protection on critical data structure, static data, privileged registers with static content. These patches present the first part where it is only possible to place these protections on memory pages. Feature-wise, this set of patches is incomplete in the sense of: - They still don't protect privileged registers - They don't protect guest TLB from malicious gva -> gpa page mappings. But they provide sketches for a basic working design. Note that I am totally noob and it took lots of time and effort to get to this point. So sorry in advance if I overlooked something.
