I'm kind of surprised that there's still no hypercall for mark_kernel_ro() that marks the kernel code read-only in the hypervisor page table such that even if someone finds a gadget to make it writable again it won't work in a VM situation - are there hypervisors that automatically detect this case and do it implicitly?
