In the dirty_log_test guest code, exit to userspace only when the vCPU is explicitly told to stop. Periodically exiting just to check if a flag has been set is unnecessary, weirdly complex, and wastes time handling exits that could be used to dirty memory. Opportunistically convert 'i' to a uint64_t to guard against the unlikely scenario that guest_num_pages exceeds the storage of an int.

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.
