Sean Christopherson 73ad160693 KVM: x86/mmu: WARN on NULL pae_root or lm_root, or bad shadow root level ... WARN if KVM is about to dereference a NULL pae_root or lm_root when loading an MMU, and convert the BUG() on a bad shadow_root_level into a WARN (now that errors are handled cleanly). With nested NPT, botching the level and sending KVM down the wrong path is all too easy, and the on-demand allocation of pae_root and lm_root means bugs crash the host. Obviously, KVM could unconditionally allocate the roots, but that's arguably a worse failure mode as it would potentially corrupt the guest instead of crashing it.
