Patch series "arch: make PxD_ORDER generically available", v2. The question what does PxD_ORDER define raises from time to time and there is still a conflict between MIPS and DAX definitions. Some time ago Matthew Wilcox suggested to use PMD_TABLE_ORDER to define the order of page table allocation: [1] https://lore.kernel.org/linux-arch/YPCJftSTUBEnq2lI@casper.infradead.org/ The parisc patch made it in, but mips didn't. Now mips defines from asm/include/pgtable.h were copied to loongarch which made it worse. Let's deal with it once and for all and rename PxD_ORDER defines to PxD_TABLE_ORDER or just drop them when the only possible order of page table is 0. This patch (of 15): This is the order of the page table allocation, not the order of a PTE. Since its always hardwired to 0, simply drop it.

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 Restructured Text 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.
