:kyb: is an extra markup that we should avoid when we can.
It worsens the plain-text reading experience and adds very little value
to rendered views.
Remove all :kbd: tags from Documentation/*

Module kgdb had been converted to debug_core since commit c433820971ff
("Move kernel/kgdb.c to kernel/debug/debug_core.c") be added, so let's
correct the module parameter path.

Using set remotebaud to set the baud rate was deprecated in
gdb-7.7 and completely removed from the command parser in gdb-7.8
(released in 2014). Adopt set serial baud instead.

Most readers are probably going to figure out that the config is actually
all upper-case letters, as all Kconfig symbols are this way.
Properly capitalizing makes the script ./scripts/checkkconfigsymbols.py
happy, which otherwise would report this as a reference to a non-existing
Kconfig symbol.
So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb
documentation.

Which Sphinx 3, :c:type: can't be used anymore for structs,
as this should be used only for typedefs.
Rely on automarkup.py for struct references.
This file has an special case, though: it uses the tag also
to point to an array. Let's use, instead, :c:expr: for such
purpose, as it should do the right thing.
This should fix this warning:
./Documentation/dev-tools/kgdb.rst:875: WARNING: Unparseable C cross-reference: 'kdb_poll_funcs[]'
Invalid C declaration: Expected end of definition. [error at 14]
kdb_poll_funcs[]

The recent patch ("kgdboc: Add kgdboc_earlycon to support early kgdb
using boot consoles") adds a new kernel command line parameter.
Document it.
Note that the patch adding the feature does some comparing/contrasting
of "kgdboc_earlycon" vs. the existing "ekgdboc". See that patch for
more details, but briefly "ekgdboc" can be used _instead_ of "kgdboc"
and just makes "kgdboc" do its normal initialization early (only works
if your tty driver is already ready). The new "kgdboc_earlycon" works
in combination with "kgdboc" and is backed by boot consoles.

commit 6807c84652b0 ("x86: Enable KASLR by default") enables KASLR
by default on x86. While KASLR will confuse gdb which resolve kernel
symbol address from symbol table of vmlinux. We should turn off KASLR for
kernel debugging.

The automatic conversion didn't work too well for this file.
It added weird html blocks inside it, and did some weird
things for literals. Manually fix it, in order to present
a nice display at html/pdf outputs.
