mainlining shenanigans
Move the handing of the point of no return from search_binary_handler into __do_execve_file so that it is easier to find, and to keep things robust in the face of change. Make it clear that an existing fatal signal will take precedence over a forced SIGSEGV by not forcing SIGSEGV if a fatal signal is already pending. This does not change the behavior but it saves a reader of the code the tedium of reading and understanding force_sig and the signal delivery code. Update the comment in begin_new_exec about where SIGSEGV is forced. Keep point_of_no_return from being a mystery by documenting what the code is doing where it forces SIGSEGV if the code is past the point of no return.

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.
