    KVM: nVMX: always update CR3 in VMCS · df7e0681
    Paolo Bonzini authored
    vmx_load_mmu_pgd is delaying the write of GUEST_CR3 to prepare_vmcs02 as
    an optimization, but this is only correct before the nested vmentry.
    If userspace is modifying CR3 with KVM_SET_SREGS after the VM has
    already been put in guest mode, the value of CR3 will not be updated.
    Remove the optimization, which almost never triggers anyway.
    
    Fixes: 04f11ef4 ("KVM: nVMX: Always write vmcs02.GUEST_CR3 during nested VM-Enter")
