IRQ_WORK_FLAGS is defined simply to 3UL. This is confusing as it says nothing about its purpose. Define IRQ_WORK_FLAGS as a bitwise OR of IRQ_WORK_PENDING and IRQ_WORK_BUSY and change its name to IRQ_WORK_CLAIMED. While we're at it: use the BIT() macro for all flags.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
