Paul Burton b87281e7f2 irqchip/mips-gic: Remove device IRQ domain 
In commit c98c1822ee ("irqchip/mips-gic: Add device hierarchy domain")
Qais indicates that he felt having a separate device IRQ domain was
cleaner, but along with everyone else I'm aware of touching this driver
I disagree.

Remove the separate device IRQ domain so that we simply have the main
GIC IRQ domain used for devices, and an IPI IRQ domain as a child. The
logic for handling the device interrupts & IPIs is cleanly separated
into the appropriate domain ops, making it much easier to reason about
what the driver is doing than the previous approach where the 2 child
domains had to call up to their parent, which had to handle both types
of interrupt & had all sorts of weird & wonderful duplication or
outright clobbering of setup performed by multiple domains.

README 

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.
