Increment the "hypercalls" stat for KVM hypercalls as soon as KVM knows it will skip the guest instruction, i.e. once KVM is committed to emulating the hypercall. Waiting until completion adds no known value, and creates a discrepancy where the stat will be bumped if KVM exits to userspace as a result of trying to skip the instruction, but not if the hypercall itself exits. Handling the stat in common code will also avoid the need for another helper to dedup code when TDX comes along (TDX needs a separate completion path due to GPR usage differences).

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 reStructuredText 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.
