Randy Dunlap b689622cc4 TOMOYO: fix __setup handlers return values
[ Upstream commit 39844b7e3084baecef52d1498b5fa81afa2cefa9 ]

__setup() handlers should return 1 if the parameter is handled.
Returning 0 causes the entire string to be added to init's
environment strings (limited to 32 strings), unnecessarily polluting it.

Using the documented strings "TOMOYO_loader=string1" and
"TOMOYO_trigger=string2" causes an Unknown parameter message:
  Unknown kernel command line parameters
    "BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 \
     TOMOYO_trigger=string2", will be passed to user space.

and these strings are added to init's environment string space:
  Run /sbin/init as init process
    with arguments:
     /sbin/init
    with environment:
     HOME=/
     TERM=linux
     BOOT_IMAGE=/boot/bzImage-517rc5
     TOMOYO_loader=string1
     TOMOYO_trigger=string2

With this change, these __setup handlers act as expected,
and init's environment is not polluted with these strings.

README

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.
