Introduce gsi_irq_setup() and gsi_irq_teardown() to disable all GSI interrupts when first setting up GSI hardware, and to clean things up when we're done. Re-enable all GSI interrupt types in gsi_irq_enable(), but do so only after each of the type-specific interrupt masks has been configured. Similarly, disable all interrupt types in gsi_irq_disable()--first--before zeroing out the type-specific masks.

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.
