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.

Pull irq fix from Ingo Molnar:
"Restore unintentionally lost quirk settings in the GIC irqchip driver,
which broke certain devices"

perf/core: Fix potential NULL deref
When splitting the allocation of the ITS node from its configuration,
some of the default settings were kept in the latter instead of
being moved to the former.
This has the side effect of negating some of the quirk detections that
have happened in between, amongst which the dreaded Synquacer hack
(that also affect Dominic's TI platform).
Move the initialisation of these fields early, so that they can again be
overriden by the Synquacer quirk.

Pull irqchip fixes from Marc Zyngier:
- DT binding updates for Renesas r8a779f0 and rzg2l
- Let GICv3 honor the "dma-non-coherent" attribute for systems that
rely on SW guessing what the HW supports
- Fix the RISC-V INTC probing by marking all devices as initialised
at once
- Properly translate interrupt numbers from DT on stm32-exti
- Use irq_data_get_irq_chip_data() in the rzg2l driver instead of
blindly dereferencing the irq_data structure
- Add a MAINTAINERS entry for the various ARM GIC irqchip drivers

swiotlb: do not try to allocate a TLB bigger than MAX_ORDER pages
Recent changes to count number of matching symbols when creating
a kprobe event failed to take into account kernel modules. As such, it
breaks kprobes on kernel module symbols, by assuming there is no match.
Fix this my calling module_kallsyms_on_each_symbol() in addition to
kallsyms_on_each_match_symbol() to perform a proper counting.

It is pretty obvious that I haven't done much on the IRQ side
for a while, and it is unlikely that I'll have more bandwidth
for it any time soon. People keep sending me patches that
I end-up reviewing in a cursory manner, which isn't great for
anyone.
So in everyone's interest, I'm removing myself from the list
of maintainers and leave the irqchip and irqdomain subsystems
in Thomas' capable hands.

When allocating a new pool at runtime, reduce the number of slabs so
that the allocation order is at most MAX_ORDER. This avoids a kernel
warning in __alloc_pages().
The warning is relatively benign, because the pool size is subsequently
reduced when allocation fails, but it is silly to start with a request
that is known to fail, especially since this is the default behavior if
the kernel is built with CONFIG_SWIOTLB_DYNAMIC=y and booted without any
swiotlb= parameter.
