Currently, APF mechanism relies on the #PF abuse where the token is being passed through CR2. If we switch to using interrupts to deliver page-ready notifications we need a different way to pass the data. Extent the existing 'struct kvm_vcpu_pv_apf_data' with token information for page-ready notifications. While on it, rename 'reason' to 'flags'. This doesn't change the semantics as we only have reasons '1' and '2' and these can be treated as bit flags but KVM_PV_REASON_PAGE_READY is going away with interrupt based delivery making 'reason' name misleading. The newly introduced apf_put_user_ready() temporary puts both flags and token information, this will be changed to put token only when we switch to interrupt based notifications.

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.
