Subject[PATCH v2] kbuild: verify that $DEPMOD is installed
Date
From: Randy Dunlap <rdunlap@infradead.org>

Verify that 'depmod' ($DEPMOD) is installed.
This is a partial revert of 620c231c7a7f (from 2012):
("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
