Jiaxun Yang b6db4ef5ea irqchip/mips-gic: Don't touch vl_map if a local interrupt is not routable
commit 2c6c9c049510163090b979ea5f92a68ae8d93c45 upstream.

When a GIC local interrupt is not routable, it's vl_map will be used
to control some internal states for core (providing IPTI, IPPCI, IPFDC
input signal for core). Overriding it will interfere core's intetrupt
controller.

Do not touch vl_map if a local interrupt is not routable, we are not
going to remap it.

Before dd098a0e0319 (" irqchip/mips-gic: Get rid of the reliance on
irq_cpu_online()"), if a local interrupt is not routable, then it won't
be requested from GIC Local domain, and thus gic_all_vpes_irq_cpu_online
won't be called for that particular interrupt.

Fixes: dd098a0e0319 (" irqchip/mips-gic: Get rid of the reliance on irq_cpu_online()")

README

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.
