Subject: [PATCH 4.14 04/22] kbuild: verify that $DEPMOD is installed

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Randy Dunlap <rdunlap@...radead.org>

commit 934193a654c1f4d0643ddbf4b2529b508cae926e upstream.

Verify that 'depmod' ($DEPMOD) is installed.
This is a partial revert of commit 620c231c7a7f
("kbuild: do not check for ancient modutils tools").

Also update Documentation/process/changes.rst to refer to
kmod instead of module-init-tools.

Fixes kernel bugzilla #198965:
https://bugzilla.kernel.org/show_bug.cgi?id=198965
