Get the gfn, size, and hva from the new memslot instead of the userspace memory region when preparing/committing memory region changes. This will allow a future commit to drop the @mem param. Note, this has a subtle functional change as KVM would previously reject DELETE if userspace provided a garbage userspace_addr or guest_phys_addr, whereas KVM zeros those fields in the "new" memslot when deleting an existing memslot. Arguably the old behavior is more correct, but there's zero benefit into requiring userspace to provide sane values for hva and gfn.

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.
