Revert "arm64: Increase the max granular size"
This reverts commit 97303480. Commit 97303480 ("arm64: Increase the max granular size") increased the cache line size to 128 to match Cavium ThunderX, apparently for some performance benefit which could not be confirmed. This change, however, has an impact on the network packet allocation in certain circumstances, requiring slightly over a 4K page with a significant performance degradation. The patch reverts L1_CACHE_SHIFT back to 6 (64-byte cache line).
