Subject: checkpatch: mark kunmap() and kunmap_atomic() deprecated
Date: Thu, 29 Dec 2022 14:17:15 -0800

It was suggested by Fabio that kunmap() be marked deprecated in
checkpatch.[1] This did not seem necessary until an invalid conversion of
kmap_local_page() appeared in mainline.[2][3] The introduction of this bug
would have been flagged with kunmap() being marked deprecated.

Add kunmap() and kunmap_atomic() to checkpatch to help prevent further
confusion.
