AOSP only supports running tests loaded with modules. Built-in
test execution support has been disabled. In addition, in order
to fully enable running module loaded tests both CONFIG_KUNIT
needs to be enabled and kernel command line argument
`kunit.enable` needs to be set to 1.
The remaining KUnit documentation has been left as-is.
This section details the kernel unit testing framework.

* Use the common helper instead of a raw WRITE_ONCE as
* the SPTE needs to be updated atomically if it can be
* modified by a different vCPU outside of mmu_lock.
* Even though the parent SPTE is !PRESENT, the TLB
* hasn't yet been flushed, and both Intel and AMD
* document that A/D assists can use upper-level PxE
* entries that are cached in the TLB, i.e. the CPU can
* still access the page and mark it dirty.
*
* No retry is needed in the atomic update path as the
* sole concern is dropping a Dirty bit, i.e. no other
* task can zap/remove the SPTE as mmu_lock is held for
* write. Marking the SPTE as a removed SPTE is not
* strictly necessary for the same reason, but using
* the remove SPTE value keeps the shared/exclusive
* paths consistent and allows the handle_changed_spte()
* call below to hardcode the new value to REMOVED_SPTE.
*
* Note, even though dropping a Dirty bit is the only
* scenario where a non-atomic update could result in a
* functional bug, simply checking the Dirty bit isn't
* sufficient as a fast page fault could read the upper
* level SPTE before it is zapped, and then make this
* target SPTE writable, resume the guest, and set the
* Dirty bit between reading the SPTE above and writing
