Linux kernel source tree

This gives the quote! macro support for the following additional tokens:
* The = token.
* The _ token.
* The # token. (when not followed by an identifier)
* Using #my_var with variables of type Ident.
Additionally, some type annotations are added to allow cases where
groups are empty. For example, quote! does support () in the input, but
only when it is *not* empty. When it is empty, there are zero `.push`
calls, so the compiler can't infer the item type and also emits a
warning about it not needing to be mutable.
These additional quote! features are used by a new proc macro that
generates code looking like this:
const _: () = {
if true {
::kernel::bindings::#name
} else {
#name
};
};
where #name has type Ident.

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 reStructuredText 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.
