The use of kmap_atomic/kunmap_atomic is deprecated. The purpose of
kmap-like functions is to create temporary mappings.

kmap_atomic() typically disables preemption, while kmap_local_page()
allows preemption.

According to the documentation, kmap_atomic() is primarily necessary
for contexts that cannot sleep.

kmap_atomic() may also be used by interrupt contexts, since it does
not sleep and the callers too may not sleep until after
kunmap_atomic() is called.

kunmap_atomic() may implicitly depend on the side effects of atomic
mappings, i.e. disabling page faults or preemption, or both. In that
case, explicit calls to pagefault_disable() or preempt_disable() or
both must be made in conjunction with the use of kmap_local_page().
