Update the guest state and timing entry/exit accounting to use the new API, which was introduced following issues found[1]. KVM HV does possibly call instrumented code inside the guest context, and it does call srcu inside the guest context which is fragile at best. Switch to the new API, moving the guest context inside the srcu_read_lock/unlock region.

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.
