Yes, we will review changes and check performance/accuracy in our internal validation

We've run first performance and functional tests and this PR passed everything with expected results. We will run one more test on other platform, to make sure that everything is ok. Tests will be finished by the end of this week. Meanwhile we tried to migrate softmax kernel with changes from this branch and everything is working as expected 👍 https://github.com/PaddlePaddle/Paddle/pull/47339

@Silv3S Hello, are the tests finished?

[Silv3S]

LGTM There are small differences in accuracy (some positive, some negative). We will run more test after this PR is merged, as they are more stable.
