Only the call from do_sigbus will send SIGBUS due to a memory machine check error. Consolidate all of the machine check signal generation code in do_sigbus and remove the now unnecessary fault parameter from force_sig_info_fault. Explicitly use the now constant si_code BUS_ADRERR in the call to force_sig_info_fault from do_sigbus. This makes the code in arch/x86/mm/fault.c easier to follower and simpler to maintain.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
