Starting with IPA v5.0, a single IPA instance can have more than 32 endpoints defined. To handle this, each register that holds a bitmap of IPA endpoints is replicated as needed to represent the available endpoints. To prepare for this, registers that represent endpoint IDs in a bit mask will be defined to have a parameter, with a stride value of 4 bytes. The first 32 endpoints are represented in the first 32-bit register, then the next (up to) 32 endpoints at an offset 4 bytes higher. When accessing such a register, the endpoint ID divided by 32 determines the offset, and the endpoint ID modulo 32 defines the endpoint's bit position within the register. The first two registers we'll update for this are STATE_AGGR_ACTIVE and AGGR_FORCE_CLOSE. Until more than 32 endpoints are supported, this change has no practical effect.

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.
