RISCV uses a global variable pfn_base for page/pfn translation. But this is a common name and will be used elsewhere. In those cases, the page-pfn macros which refer to this name will be referred to the local/input variable instead. (such as in vfio_pin_pages_remote). This make everything wrong. This patch changes the name from pfn_base to riscv_pfn_base to fix this problem. Signed-off-by: Kenneth Lee <liguozhu@hisilicon.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>
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.
