commit 7de712ccc096b81d23cc0a941cd9b8cb3956605d upstream. While working on changing this code to use force_sig_fault I discovered that do_unaliged_user is sets si_signo to SIGBUS and passes SIGSEGV to force_sig_info. Which is just b0rked. The code is reporting a SIGBUS error so replace the SIGSEGV with SIGBUS.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
