Remarks
The difference between __ptcl and __ptcg is that __ptcl affects the local processor, where __ptcg affects all processors in the coherence ___domain.
For appropriate use of these instructions, see the Intel IPF documentation.
These functions are only available in kernel mode and are only available as intrinsics.
