Alessio Belle bdced61365 drm/imagination: Mask GPU IRQs in threaded handler
Pass IRQF_ONESHOT flag to request_threaded_irq(), so that interrupts will
be masked by the kernel until the end of the threaded IRQ handler. Since
the calls to pvr_fw_irq_enable() and pvr_fw_irq_disable() are now
redundant, remove them.

Interrupts to the host from the soon-to-be-added RISC-V firmware
processors cannot be masked in hardware. This change allows us to continue
using the threaded handler in GPUs with a RISC-V firmware.

For simplicity, the same approach is taken for all firmware processors.

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 reStructuredText 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.
