[Where problems could occur] The first commit reverts the patch that didn't find its way to upstream. The second to forth commits are to enable DG1 which applied for solving conflicts. The fifth and sixth commit splits code for EHL and JSL. The seventh and eighth commits rename enums, no function changes. The ninth commit is newer version of the first reverted commit. The tenth commit adds CML CPU support on TGP PCH which fixes this issue. According to the above explanation, 1. the DG1 in newly enabled by commits 2 to 4, no regression could occur, 2. the EHL and JSL commits are pretty simple and straightforward, should be safe to include, 3. the first commit is equivalence to the ninth commit 4. the tenth commit is pretty simple to add GEN9 into flow control, so I think there should be no problems could occur from this patchset.
