Randy Dunlap 9eeee6f684 ACPI: APEI: fix return value of __setup handlers
[ Upstream commit f3303ff649dbf7dcdc6a6e1a922235b12b3028f4 ]

__setup() handlers should return 1 to indicate that the boot option
has been handled. Returning 0 causes a boot option to be listed in
the Unknown kernel command line parameters and also added to init's
arg list (if no '=' sign) or environment list (if of the form 'a=b').

Unknown kernel command line parameters "erst_disable
  bert_disable hest_disable BOOT_IMAGE=/boot/bzImage-517rc6", will be
  passed to user space.

 Run /sbin/init as init process
   with arguments:
     /sbin/init
     erst_disable
     bert_disable
     hest_disable
   with environment:
     HOME=/
     TERM=linux
     BOOT_IMAGE=/boot/bzImage-517rc6

Fixes: a08f82d080 ("ACPI, APEI, Error Record Serialization Table (ERST) support")
Fixes: 9dc9666416 ("ACPI, APEI, HEST table parsing")

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.
