On PowerPC architecture, calling disable_irq_nosync from IRQ context is not providing the required effect. In current megaraid_sas driver, disable_irq_nosync is being called from IRQ context before enabling IRQ poll. But due to the issue seen on PPC, after IRQ poll disable and legacy ISR is enabled, we are not seeing our ISR getting called. Fix: Call disable_irq from IRQ poll thread context instead of IRQ context.

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.
