 # Build the kernel release string
-# The KERNELRELEASE is stored in a file named include/config/kernel.release

-# Take the contents of any files called localversion* and the config
-# variable CONFIG_LOCALVERSION and append them to KERNELRELEASE.

+# The KERNELRELEASE value built here is stored in the file
+# include/config/kernel.release, and is used when executing several
+# make targets, such as "make install" or "make modules_install."
+#
+# The eventual kernel release string consists of the following fields,
+# shown in a hierarchical format to show how smaller parts are concatenated
+# to form the larger and final value, with values coming from places like
+# the Makefile, kernel config options, make command line options and/or

+#	    $(LOCALVERSION)		(from make command line if provided)

+#  Note how the final $(localver-auto) string is included *only* if the
+# kernel config option CONFIG_LOCALVERSION_AUTO is selected.  Also, at the
+# moment, only git is supported but other SCMs can edit the script
+# scripts/setlocalversion and add the appropriate checks as needed.
