In order to debug the kernel successfully with gdb you need to run
'make scripts_gdb' nowadays.
This was changed with the following commit:
Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb
constants.py")
In order to have a complete guide for beginners this remark
should be added to the offial documentation.

Some documents that listed on subsystem-apis have 'Linux' or 'The Linux'

The device specific directory in debugfs does not have "accel". For
example, the documentation says device 0 should have a debugfs entry as
/sys/kernel/debug/accel/accel0/ but in reality the entry is
/sys/kernel/debug/accel/0/
Fix the documentation to match the implementation.

The Sphinx 2.4 release is three years old, and it is becoming increasingly
difficult to even find a system with an sufficiently archaic Python
installation that can run versions older than that. I can no longer test
changes against anything prior to 2.4.x.
Move toward raising our minimum Sphinx requirement to 2.4.x so we can
delete some older support code and claim to support a range of versions
that we can actually test.
In the absence of screams, the actual removal of support can happen later
in 2023.

Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process. They *did* warn us... Just open-code the
functionality as is done in Sphinx itself.
Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.

It is finally becoming increasingly rare to find a distribution that
still ships with gnupg-1.x, so remove the last vestiges of "gpg" vs
"gpg2" from documentation.
Similarly, starting with GnuPG 2.2 and above, the default --gen-key
operation creates ed25519/cv25519 keypairs, so update all example
command outputs to use that combination instead of rsa2048.
Lastly, add a few wording tweaks and remove links that lead to stale
information (e.g. hardware tokens overview from 2017).
