使用开源代码可否遵守开源协议？

在 https://github.com/PaddlePaddle/Anakin/issues/527 里面 @yiicy 说

感谢指出问题，我们最开始的GEMM借鉴了compute library，现在sgemm.cpp里的接口已经弃用了，统一使用sgemm_prepacked.cpp里的接口，实现上也做了相应的变化，sgemm_prepacked.cpp的xblock将按照l2 cache大小划分

我理解为你们承认了你们使用了 acl 的开源代码，那么请遵守它们的 MIT 协议。没有人关心你们的 block 怎么划分

在同一个 issue 里面，@throneclay 说

没人回复这个就关了，如果有问题可以随时跟我们联系

我和 @izp001 都进一步回复了，请你们也正面给出回应

完了，大缺要怼到底了。最好还是撤回代码...最近刚好没啥出轨的新闻。

之前paddle-mobile的int8抄袭ncnn int8的，后面可是删除相关代码并做出了书面道歉的哟，希望贵组能准守开源协议的游戏规则。

附上相关代码

Anakin: https://github.com/PaddlePaddle/Anakin/blob/bc5ac0a03798d36826478855b1083562e633e979/saber/funcs/impl/arm/neon/impl/sgemm_arm.cpp#L565

ACL（随手搜到的）: https://github.com/ARM-software/ComputeLibrary/blob/52ba29e936b8e711e8acdfe819e36f884d4f3fe1/src/core/NEON/kernels/arm_gemm/kernels/a32_sgemm_8x6/a53.cpp#L32

可以看到注释是一样的，借鉴的痕迹也很明显

非常抱歉此问题带来的困扰。 添加和整合sgemm_arm这部分代码的目的是用来对比sgemm的性能，在基线对照代码的整理过程中，疏漏掉了里面ACL开源代码对应的MIT License，我们已对应加上license。 由于sgemm_arm.cpp、sgemm_arm.h只用于之前的对比测试，并未在Anakin其他代码中调用使用，会从repo中删除。 我们以后会对代码规范做更严格检查，感谢daquexian的监督和反馈。

改了就挺好，赞。 顺带提一句，anakin 这个名字并不讨喜，甚至有点令人反感，看完《星球大战》全集应该知道黑武士灭了多少人。好比有人给自己起名叫“王魔”、“李鬼“。

Fixed by #533, Thanks!
