Loading CR3 as part of emulating vmentry is different from regular CR3 loads, as implemented in kvm_set_cr3, in several ways. * different rules are followed to check CR3 and it is desirable for the caller to distinguish between the possible failures * PDPTRs are not loaded if PAE paging and nested EPT are both enabled * many MMU operations are not necessary This patch introduces nested_vmx_load_cr3 suitable for CR3 loads as part of nested vmentry and vmexit, and makes use of it on the nested vmentry path.
