Use the generic infrastructure to check for and handle pending work before transitioning into guest mode. This now handles TIF_NOTIFY_RESUME as well which was ignored so far. Handling it is important as this covers task work and task work will be used to offload the heavy lifting of POSIX CPU timers to thread context.

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.
