Linus Torvalds cec6937dd1 task_work: make TWA_NMI_CURRENT handling conditional on IRQ_WORK 
The TWA_NMI_CURRENT handling very much depends on IRQ_WORK, but that
isn't universally enabled everywhere.

Maybe the IRQ_WORK infrastructure should just be unconditional - x86
ends up indirectly enabling it through unconditionally enabling
PERF_EVENTS, for example.  But it also gets enabled by having SMP
support, or even if you just have PRINTK enabled.

But in the meantime TWA_NMI_CURRENT causes tons of build failures on
various odd minimal configs.  Which did show up in linux-next, but
despite that nobody bothered to fix it or even inform me until -rc1 was
out.

Fixes: 466e4d801c ("task_work: Add TWA_NMI_CURRENT as an additional notify mode")

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.
