We currently don't use the maintenance interrupt very much, apart from EOI on level interrupts, and for LR underflow in limited cases. However, as we are moving toward a setup where active interrupts can live outside of the LRs, we need to use the MIs in a more diverse set of cases. Add a new helper that produces a digest of the ap_list, and use that summary to set the various control bits as required. This slightly changes the way v2 SGIs are handled, as they used to count for more than one interrupt, but not anymore.

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 reStructuredText 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.
