Brian Norris 63e444e45c genirq/test: Drop CONFIG_GENERIC_IRQ_MIGRATION assumptions 
[ Upstream commit add03fdb9d ]

Not all platforms use the generic IRQ migration code, even if they select
GENERIC_IRQ_MIGRATION. (See, for example, powerpc / pseries_cpu_disable().)

If such platforms don't perform managed shutdown the same way, the interrupt
may not actually shut down, and these tests fail:

[    4.357022][  T101]     Expected irqd_is_activated(data) to be false, but is true

[    4.376088][  T101]     Expected irqd_is_started(data) to be false, but is true

[    4.378073][    T1] # irq_test_cases: pass:3 fail:1 skip:0 total:4

Rather than test that PowerPC performs migration the same way as the
unterrupt core, just drop the state checks. The point of the test was to
ensure that the code kept |depth| balanced, which still can be tested for.

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.
