It seems there is about 24Bytes binary size increase for __page_frag_cache_refill() after refactoring in arm64 system with 64K PAGE_SIZE. By doing the gdb disassembling, It seems we can have more than 100Bytes decrease for the binary size by using __alloc_pages() to replace alloc_pages_node(), as there seems to be some unnecessary checking for nid being NUMA_NO_NODE, especially when page_frag is part of the mm system.
