      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.

      This was was added in commit 689f3bf2 ("KVM: x86: unify callbacks
      to load paging root", 2020-03-16) just to keep the two vendor-specific
      modules closer, but we'll fix VMX too.

      KVM: nSVM: correctly inject INIT vmexits · 5b672408
      Paolo Bonzini authored
      The usual drill at this point, except there is no code to remove because this
      case was not handled at all.

      KVM: nSVM: remove exit_required · bd279629
      Paolo Bonzini authored
      All events now inject vmexits before vmentry rather than after vmexit.  Therefore,
      exit_required is not set anymore and we can remove it.
