The other stress test programs provide a SIGUSR1 handler which modifies the live register state in order to validate that signal context is being restored during signal return. While we can't usefully do this when testing kernel mode FP usage provide a handler for SIGUSR1 which just counts the number of signals like we do for SIGUSR2, allowing fp-stress to treat all the test programs uniformly.

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 reStructuredText 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.
