virt_to_phys() doesn't need the address pointer to be mutable. At the same time allowing it to be mutable leads to the following build warning for constant pointers: warning: passing argument 1 of ‘virt_to_phys’ discards ‘const’ qualifier from pointer target type Signed-off-by: Stanislav Kinsburskii <stanislav.kinsburskii@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/168155747391.13678.10634415747614468991.stgit@skinsburskii.localdomain
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.
