[ Upstream commit622d9b5577] In the genpd governor we walk the list of child-domains to take into account their next_wakeup. If the child-domain itself, doesn't have a governor assigned to it, we can end up using the next_wakeup value before it has been properly initialized. To prevent a possible incorrect behaviour in the governor, let's initialize next_wakeup to KTIME_MAX.

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.
