Kumar Kartikeya Dwivedi 4fec4c22f0 selftests/bpf: Add IRQ save/restore tests
Include tests that check for rejection in erroneous cases, like
unbalanced IRQ-disabled counts, within and across subprogs, invalid IRQ
flag state or input to kfuncs, behavior upon overwriting IRQ saved state
on stack, interaction with sleepable kfuncs/helpers, global functions,
and out of order restore. Include some success scenarios as well to
demonstrate usage.

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.
