When soft interrupt actions are called, they are passed a pointer to the struct softirq action which contains the action's function pointer. This pointer isn't useful, as the action callback already knows what function it is. And since each callback handles a specific soft interrupt, the callback also knows which soft interrupt number is running. No soft interrupt action callback actually uses this parameter, so remove it from the function pointer signature. This clarifies that soft interrupt actions are global routines and makes it slightly cheaper to call them.

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.
