On HiSilicon uncore PMU drivers, interrupt handling function and interrupt registration function are very similar in differents PMU modules. Let's refactor the frame. Two new callbacks are added for the HW accessors: * hisi_uncore_ops::get_int_status returns a bitmap of events which have overflowed and raised an interrupt * hisi_uncore_ops::clear_int_status clears the overflow status for a specific event These callback functions are used by a common IRQ handler, hisi_uncore_pmu_isr(). One more function hisi_uncore_pmu_init_irq() is added to replace each PMU initialization IRQ interface and simplify the code.

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.
