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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
