The method used to decode asynchronous interrupts involves unnecessary loops to match up bits that are set with corresponding entries in the asynchronous interrupt information table. This algorithm is wasteful and does not scale well as new status bits are supported. As an improvement, use the for_each_set_bit() service to iterate over the asynchronous status bits and refactor the information table such that it can be indexed by bit position.

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.
