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.

Commit 16ce101d ("mm/memory.c: fix race when faulting a device private page") changed the migrate_to_ram() callback to take a reference on the device page to ensure it can't be freed while handling the fault. Unfortunately the corresponding update to Nouveau to accommodate this change was inadvertently dropped from that patch causing GPU to CPU migration to fail so add it here.
