The current rcu_gp_kthread_wake() function uses in_interrupt() and thus does a self-wakeup from all interrupt contexts, including the pointless case where the GP kthread happens to be running with bottom halves disabled, along with the impossible case where the GP kthread is running within an NMI handler (you are not supposed to invoke rcu_gp_kthread_wake() from within an NMI handler. This commit therefore replaces the in_interrupt() with in_irq(), so that the self-wakeups happen only from handlers for hardware interrupts and softirqs. This also makes the code match the comment.

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.
