Pull irq affinity fixes from Thomas Gleixner:
- Fix error path handling in the affinity spreading code
- Make affinity spreading smarter to avoid issues on systems which
claim to have hotpluggable CPUs while in fact they can't hotplug
anything.
So instead of trying to spread the vectors (and thereby the
associated device queues) to all possibe CPUs, spread them on all
present CPUs first. If there are left over vectors after that first
step they are spread among the possible, but not present CPUs which
keeps the code backwards compatible for virtual decives and NVME
which allocate a queue per possible CPU, but makes the spreading
smarter for devices which have less queues than possible or present
CPUs.
* 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/affinity: Spread irq vectors among present CPUs as far as possible
genirq/affinity: Allow irq spreading from a given starting point
genirq/affinity: Move actual irq vector spreading into a helper function
genirq/affinity: Rename *node_to_possible_cpumask as *node_to_cpumask
genirq/affinity: Don't return with empty affinity masks on error

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
