      KVM: x86 emulator: Fix segment loading in VM86 · f8da94e9
      Kevin Wolf authored
      This fixes a regression introduced in commit 03ebebeb ("KVM: x86
      emulator: Leave segment limit and attributs alone in real mode").
      
      The mentioned commit changed the segment descriptors for both real mode
      and VM86 to only update the segment base instead of creating a
      completely new descriptor with limit 0xffff so that unreal mode keeps
      working across a segment register reload.
      
      This leads to an invalid segment descriptor in the eyes of VMX, which
      seems to be okay for real mode because KVM will fix it up before the
      next VM entry or emulate the state, but it doesn't do this if the guest
      is in VM86, so we end up with:
      
        KVM: entry failed, hardware error 0x80000021
      
      Fix this by effectively reverting commit 03ebebeb
      
       for VM86 and leaving
      it only in place for real mode, which is where it's really needed.
