: non-SMP IRQ affinity fixes courtesy of Samuel Holland:
:
: "This series solves some inconsistency with how IRQ affinity masks are
: handled between SMP and non-SMP configurations.
:
: In non-SMP configs, an IRQ's true affinity is always cpumask_of(0), so
: irq_{,data_}get_affinity_mask now return that, instead of returning an
: uninitialized per-IRQ cpumask. This change makes iterating over the
: affinity mask do the right thing in both SMP and non-SMP configurations.
:
: To accomplish that:
: - patches 1-3 disable some library code that was broken anyway on !SMP
: - patches 4-7 refactor the code so that irq_{,data_}get_affinity_mask
: can return a const cpumask, since that is what cpumask_of provides
: - patch 8 drops the per-IRQ cpumask and replaces it with cpumask_of(0)"
: .
PCI: hv: Take a const cpumask in hv_compose_msi_req_get_cpu()
genirq: Provide an IRQ affinity mask in non-SMP configs
genirq: Return a const cpumask from irq_data_get_affinity_mask
genirq: Add and use an irq_data_update_affinity helper
genirq: Refactor accessors to use irq_data_get_affinity_mask
genirq: Drop redundant irq_init_effective_affinity
genirq: GENERIC_IRQ_EFFECTIVE_AFF_MASK depends on SMP
genirq: GENERIC_IRQ_IPI depends on SMP
irqchip/mips-gic: Only register IPI domain when SMP is enabled

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.
