If CONFIG_HPET=y is enabled the x86 specific HPET code should reserve at least one channel for the /dev/hpet character device, so that not all channels are absorbed for per CPU clockevent devices. Create a function to assign HPET_MODE_DEVICE so the rework of the clockevents allocation code can utilize the mode information instead of reducing the number of evaluated channels by #ifdef hackery. The function is not yet used, but provided as a separate patch for ease of review. It will be used when the rework of the clockevent selection takes place.

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.
