Intel's documentation doesn't say that leaf 4 is guaranteed to contain the
cache information if the largest standard function number is >= 4. It only
says the data is available that leaf can be queried and that if leaf 2
indicates that leaf 4 contains the data that it can be found there.
If you want the patch to be added you have to get Intel to clarify their
documentation.
