commit 866f3576a72b2233a76dffb80290f8086dc49e17 upstream. During interrupt setup we allocate interrupt vectors, walk the list of msi descriptors, and fill in the message data. Requesting more interrupts than supported on s390 can lead to an out of bounds access. When we restrict the number of interrupts we should also stop walking the msi list after all supported interrupts are handled.

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.
