The pending IPA interrupts are checked by ipa_isr_thread(), and interrupts are processed only if an enabled interrupt has a condition pending. But ipa_interrupt_process_all() now makes the same check, so the one in ipa_isr_thread() can just be skipped. Also in ipa_isr_thread(), any interrupt conditions pending which are not enabled are cleared. Here too, ipa_interrupt_process_all() now clears such excess interrupt conditions, so ipa_isr_thread() doesn't have to. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

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.
