Suggestion for Kernel security: BsdGuard

Hey guys!

While testing some things in the FreeBSD Kernel, I saw some functions for
reading and modifying control registers like Cr0, where bit 16 WP ensures
protection of Kernel memory pages against "malicious" writing. Thinking
about this, I had the idea to implement code to act as a Guard in the
FreeBSD Kernel. I named it "BsdGuard". The idea is for it to check
processor registers like Cr0 and even MSRs like LSTAR and verify if these
registers have been compromised for malicious purposes. I already have a
small "layman's" demonstration of the code, which is already running in my
kernel as a module. It's worth noting that, since my studies were all based
on arch AMDx64, I don't know how the implementation would be for other
architectures like "Arm", etc. Anyway, I believe it's a good idea to
implement it in the FreeBSD kernel; I can submit a PR to freebsd/SRC.

Finally, I'm a new contributor and a new FreeBSD user, so please forgive me
if the project itself doesn't focus on this "level of control."
