[ Upstream commit 6be6cba9c4371d27f78d900ccfe34bb880d9ee20 ]
The mbigen interrupt chip has its per node registers located in a
contiguous region of page sized chunks. The code maps them into virtual
address space as a contiguous region and determines the address of a node
by using the node ID as index.
mbigen chip
|-----------------|------------|--------------|
mgn_node_0 mgn_node_1 ... mgn_node_i
|--------------| |--------------| |----------------------|
[0x0000, 0x0x0FFF] [0x1000, 0x1FFF] [i*0x1000, (i+1)*0x1000 - 1]
This works correctly up to 10 nodes, but then fails because the 11th's
array slot is used for the MGN_CLEAR registers.
mbigen chip
|-----------|--------|--------|---------------|--------|
mgn_node_0 mgn_node_1 ... mgn_clear_register ... mgn_node_i
|-----------------|
[0xA000, 0xAFFF]
Skip the MGN_CLEAR register space when calculating the offset for node IDs
greater than or equal to ten.

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.
