Torture test the cases where the runstate crosses a page boundary, and and especially the case where it's configured in 32-bit mode and doesn't, but then switching to 64-bit mode makes it go onto the second page. To simplify this, make the KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_ADJUST ioctl also update the guest runstate area. It already did so if the actual runstate changed, as a side-effect of kvm_xen_update_runstate(). So doing it in the plain adjustment case is making it more consistent, as well as giving us a nice way to trigger the update without actually running the vCPU again and changing the values.

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.
