Summary of Changes

Hello @vincentzed, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on cleaning up the codebase by removing the tile_tokens_dim parameter from several function calls. This parameter is being deprecated in future versions of FlashInfer (specifically 0.5.3 and beyond) and is currently passed as None without any functional impact. The change ensures forward compatibility with the FlashInfer library and streamlines the code by removing an unnecessary argument.

Highlights

• Code Cleanup: Removed the deprecated tile_tokens_dim parameter from various function calls across the codebase.
• FlashInfer Compatibility: Ensured compatibility with upcoming FlashInfer 0.5.3+ releases, where this parameter will no longer be accepted.
• Unused Parameter Removal: Eliminated a parameter that was already being passed as None and was unused on the FlashInfer side, simplifying the code.

Code Review

This pull request performs a clean-up by removing the deprecated tile_tokens_dim argument from calls to FlashInfer's MoE kernels across four different files. The changes are consistent and correctly applied, preparing the codebase for future updates of the FlashInfer library. The modifications are straightforward and I have no concerns.
