Marc Zyngier c351ab7bf2 soc/tegra: pmc: Don't create fake interrupt hierarchy levels
The Tegra PMC driver does ungodly things with the interrupt hierarchy,
repeatedly corrupting it by pulling hwirq numbers out of thin air,
overriding existing IRQ mappings and changing the handling flow
of unsuspecting users.

All of this is done in the name of preserving the interrupt hierarchy
even when these levels do not exist in the HW. Together with the use
of proper IRQs for IPIs, this leads to an unbootable system as the
rescheduling IPI gets repeatedly repurposed for random drivers...

Instead, let's simply mark the level from which the hierarchy does
not make sense for the HW, and let the core code trim the usused
levels from the hierarchy.

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.
