Log:
[NTOS]
- Let us know if we need to handle FPU emulation.
- The PspDeleteLdt and PspDeleteVdmObjects do not need to return anything, they just clean possible existing structures only.
- Use ExFreePoolWithTag when freeing Process->VdmObjects (help in detecting possible memory corruption).
- Since we sometimes toy with Process->VdmObjects, give a basic implementation of PspDeleteVdmObjects that just frees VdmObjects for now. Also, add an assert in PspDeleteLdt because the LdtInformation process member should remain NULL for now (since we don't use it).
