Alexander Sverdlin f0ebdfc10b MIPS: OCTEON: irq: Fix octeon_irq_force_ciu_mapping()
[ Upstream commit ba912afbd611d3a5f22af247721a071ad1d5b9e0 ]

For irq_domain_associate() to work the virq descriptor has to be
pre-allocated in advance. Otherwise the following happens:

WARNING: CPU: 0 PID: 0 at .../kernel/irq/irqdomain.c:527 irq_domain_associate+0x298/0x2e8
error: virq128 is not allocated

Use irq_alloc_desc_at() to avoid the above problem.

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.
