Linux kernel source tree

Vladimir Oltean says:
====================
DSA tagger-owned storage fixups
It seems that the DSA tagger-owned storage changes were insufficiently
tested and do not work in all cases. Specifically, the NXP Bluebox 3
(arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dts) got broken by
these changes, because
(a) I forgot that DSA_TAG_PROTO_SJA1110 exists and differs from
DSA_TAG_PROTO_SJA1105
(b) the Bluebox 3 uses a DSA switch tree with 2 switches, and the
tagger-owned storage patches don't cover that use case well, it
seems
Therefore, I'm sorry to say that there needs to be an API fixup: tagging
protocol drivers will from now on connect to individual switches from a
tree, rather than to the tree as a whole. This is more robust against
various ordering constraints in the DSA probe and teardown paths, and is
also symmetrical with the connection API exposed to the switch drivers
themselves, which is also per switch.
With these changes, the Bluebox 3 also works fine.

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.
