Jonas Gorski 5adbd7ccd4 irq-bcm6345-l1: Do not assume a fixed block to cpu mapping 
[ Upstream commit 55ad248573 ]

The irq to block mapping is fixed, and interrupts from the first block
will always be routed to the first parent IRQ. But the parent interrupts
themselves can be routed to any available CPU.

This is used by the bootloader to map the first parent interrupt to the
boot CPU, regardless wether the boot CPU is the first one or the second
one.

When booting from the second CPU, the assumption that the first block's
IRQ is mapped to the first CPU breaks, and the system hangs because
interrupts do not get routed correctly.

Fix this by passing the appropriate bcm6434_l1_cpu to the interrupt
handler instead of the chip itself, so the handler always has the right
block.

Fixes: c7c42ec2ba ("irqchips/bmips: Add bcm6345-l1 interrupt controller")

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.
