commitb383a42ca5upstream. INVALL CMD specifies that the ITS must ensure any caching associated with the interrupt collection defined by ICID is consistent with the LPI configuration tables held in memory for all Redistributors. SYNC is required to ensure that INVALL is executed. Currently, LPI configuration data may be inconsistent with that in the memory within a short period of time after the INVALL command is executed.

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.
