In an effort to clarify and simplify the annotations of assembly functions in the kernel new macros have been introduced replacing ENTRY and ENDPROC. There are separate annotations SYM_FUNC_ for normal C functions and SYM_CODE_ for other code. Currently __guest_enter and __guest_exit are annotated as standard functions but this is not entirely correct as the former doesn't do a normal return and the latter is not entered in a normal fashion. From the point of view of the hypervisor the guest entry/exit may be viewed as a single function which happens to have an eret in the middle of it so let's annotate it as such.

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.
