David Gow e6d8d31d6e kunit: Enforce task execution in {soft,hard}irq contexts 
[ Upstream commit c31f4aa8fe ]

The kunit_run_irq_test() helper allows a function to be run in hardirq
and softirq contexts (in addition to the task context). It does this by
running the user-provided function concurrently in the three contexts,
until either a timeout has expired or a number of iterations have
completed in the normal task context.

However, on setups where the initialisation of the hardirq and softirq
contexts (or, indeed, the scheduling of those tasks) is significantly
slower than the function execution, it's possible for that number of
iterations to be exceeded before any runs in irq contexts actually
occur. This occurs with the polyval.test_polyval_preparekey_in_irqs
test, which runs 20000 iterations of the relatively fast preparekey
function, and therefore fails often under many UML, 32-bit arm, m68k and
other environments.

Instead, ensure that the max_iterations limit counts executions in all
three contexts, and requires at least one of each. This will cause the
test to continue iterating until at least the irq contexts have been
tested, or the 1s wall-clock limit has been exceeded. This causes the
test to pass in all of my environments.

In so doing, we also update the task counters to atomic ints, to better
match both the 'int' max_iterations input, and to ensure they are
correctly updated across contexts.

Finally, we also fix a few potential assertion messages to be
less-specific to the original crypto usecases.

README 

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.
