If CONFIG_PHYS_ADDR_T_64BIT is not set:
drivers/dma/apple-admac.c: In function ‘admac_cyclic_write_one_desc’:
drivers/dma/apple-admac.c:213:22: error: right shift count >= width of type [-Werror=shift-count-overflow]
213 | writel_relaxed(addr >> 32, ad->base + REG_DESC_WRITE(channo));
| ^~
Fix this by using the {low,upp}er_32_bits() helper macros to obtain the
address parts.

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.
