While rv32 technically has 34-bit physical addresses, no current platforms use it and it's likely to shake out driver bugs. Let's keep 64-bit phys_addr_t off on 32-bit builds until one shows up, since other work will be needed to make such a system useful anyway. PHYS_ADDR_T_64BIT is def_bool 64BIT, so just remove the select. Signed-off-by: Olof Johansson <olof@lixom.net> 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.
