Core:
- Exclude managed interrupts in the calculation of interrupts which are
targeted to a CPU which is about to be offlined to ensure that there
are enough free vectors on the still online CPUs to migrate them over.
Managed interrupts do not need to be accounted because they are
either shut down on offline or migrated to an already reserved and
guaranteed slot on a still online CPU in the interrupts affinity
mask.
Including managed interrupts is overaccounting and can result in
needlessly aborting hibernation on large server machines.
- The usual set of small improvements
Drivers:
- Make the generic interrupt chip implementation handle interrupt
domains correctly and initialize the name pointers correctly
- Add interrupt affinity setting support to the Renesas RZG2L chip
driver.
- Prevent registering syscore operations multiple times in the SiFive
PLIC chip driver.
- Update device tree handling in the NXP Layerscape MSI chip driver

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.
