Patch series "reboot: sysfs improvements". Some improvements to the sysfs reboot interface: hide not working settings and support machines with known reboot quirks. This patch (of 2): On some machines a quirk can force a specific reboot type. Quirks are found during a DMI scan, the list of machines which need special reboot handling is defined in reboot_dmi_table. The kernel command line reboot= option overrides this via a global variable `reboot_default`, so that the reboot type requested in the command line is really performed. This was not true when setting the reboot type via the new sysfs interface. Fix this by setting reboot_default upon the first change, like reboot_setup() does for the command line.

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.
