commit7366c23ff4upstream. Building dp83640.c on arch/parisc/ produces a build warning for PAGE0 being redefined. Since the macro is not used in the dp83640 driver, just make it a comment for documentation purposes. In file included from ../drivers/net/phy/dp83640.c:23: ../drivers/net/phy/dp83640_reg.h:8: warning: "PAGE0" redefined 8 | #define PAGE0 0x0000 from ../drivers/net/phy/dp83640.c:11: ../arch/parisc/include/asm/page.h:187: note: this is the location of the previous definition 187 | #define PAGE0 ((struct zeropage *)__PAGE_OFFSET) Fixes:cb646e2b02("ptp: Added a clock driver for the National Semiconductor PHYTER.")

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.
