Since the WKTMR hardware block cannot be disabled it is necessary for the driver to accommodate for associated timing hazards. This commit targets the following possibilities: A possible race between clearing a wktmr event and the alarm expiring is made one-sided by setting the alarm to its maximum value before clearing the event. Programming alarm values close to the current time may not trigger events if the counter advances while the alarm is being programmed. After programming an alarm, a check is made to ensure that it is either in the future or an expiration event is pending.

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.
