VDSO64 cacheflush.S datapage.S gettimeofday.S and vgettimeofday.c are very similar to their VDSO32 counterpart. VDSO32 counterpart is already more complete than the VDSO64 version as it supports both PPC32 vdso and 32 bits VDSO for PPC64. Use compat macros wherever necessary in PPC32 files so that they can also be used to build VDSO64. vdso64/note.S is already a link to vdso32/note.S so no change is required.

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.
