First patch seem obvious. Second patch introduce a change in the behavior of the virtual machine in that the CRYCB is validated whenever we use or not the key masks to mimic the real machine. Patch 3 does not correct the compiled code but make more clear what is done concerning the formating of the CRYCB in the guest original CRYCB and in the shadow CRYCB.
