In preparation for folding kvm_arch_hardware_setup() into kvm_arch_init(), unwind initialization one step at a time instead of simply calling kvm_arch_exit(). Using kvm_arch_exit() regardless of which initialization step failed relies on all affected state playing nice with being undone even if said state wasn't first setup. That holds true for state that is currently configured by kvm_arch_init(), but not for state that's handled by kvm_arch_hardware_setup(), e.g. calling gmap_unregister_pte_notifier() without first registering a notifier would result in list corruption due to attempting to delete an entry that was never added to the list.

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.
