Building the xe driver for i386 results in a link time warning: x86_64-linux-ld: drivers/gpu/drm/xe/xe_migrate.o: in function `xe_migrate_vram': xe_migrate.c:(.text+0x1e15): undefined reference to `__udivdi3' Avoid this by using DIV_U64_ROUND_UP() instead of DIV_ROUND_UP(). The driver is unlikely to be used on 32=bit hardware, so the extra cost here is not too important.

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 reStructuredText 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.
