Hydra Home Agent is a device used to maintain cache coherency. Add support for explicit cache maintenance operations using it. A system has multiple of these agents. Whilst only one agent is responsible for a given cache line, interleave means that for a range operation, responsibility for the cache lines making up the range will typically be spread across multiple instances. Put this driver on a new Kconfig menu under drivers/cache. The short description as memory hotplug like operations is intended to cover the somewhat complex set of cases where this unit applies and differentiate it clearly from typical non coherent DMA flows.

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.
