This makes SMP on the vrx200 work again, by removing all the MIPS CPU
interrupt specific code and making it fully use the generic MIPS CPU
interrupt controller.
The mti,cpu-interrupt-controller from irq-mips-cpu.c now handles the CPU
interrupts and also the IPI interrupts which are used to communication
between the CPUs in a SMP system. The generic interrupt code was
already used before but the interrupt vectors were overwritten again
when we called set_vi_handler() in the lantiq interrupt driver and we
also provided our own plat_irq_dispatch() function which overwrote the
weak generic implementation. Now the code uses the generic handler for
the MIPS CPU interrupts including the IPI interrupts and registers a
handler for the CPU interrupts which are handled by the lantiq ICU with
irq_set_chained_handler() which was already called before.
Calling the set_c0_status() function is also not needed any more because
the generic MIPS CPU interrupt already activates the needed bits.

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.
