____napi_schedule() needs to be invoked with disabled interrupts due to __raise_softirq_irqoff (in order not to corrupt the per-CPU list). ____napi_schedule() needs also to be invoked from an interrupt context so that the raised-softirq is processed while the interrupt context is left. Add lockdep asserts for both conditions. While this is the second time the irq/softirq check is needed, provide a generic lockdep_assert_softirq_will_run() which is used by both caller.

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 Restructured Text 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.
