 	Assignments to $(targets) are without $(obj)/ prefix.
 	if_changed may be used in conjunction with custom commands as
 	defined in 6.7 "Custom kbuild commands".
+
 	Note: It is a typical mistake to forget the FORCE prerequisite.
+	Another common pitfall is that whitespace is sometimes
+	significant; for instance, the below will fail (note the extra space
+	after the comma):
+		target: source(s) FORCE
+	#WRONG!#	$(call if_changed, ld/objcopy/gzip)
 
     ld
 	Link target. Often LDFLAGS_$@ is used to set specific options to ld.

+	default ""
+	help
+	  This can be either a single cpio archive with a .cpio suffix or a
+	  space-separated list of directories and files for building the
+	  initramfs image.  A cpio archive should contain a filesystem archive
+	  to be used as an initramfs image.  Directories should contain a
+	  filesystem layout to be included in the initramfs image.  Files
+	  should contain entries according to the format described by the
+	  "usr/gen_init_cpio" program in the kernel tree.
+
+	  When multiple directories and files are specified then the
+	  initramfs image will be the aggregate of all of them.
+
+	  See <file:Documentation/early-userspace/README for more details.
+
+	  If you are not sure, leave it blank.

+config INITRAMFS_ROOT_UID

+	default "0"
+	help
+	  This setting is only meaningful if the INITRAMFS_SOURCE is
+	  contains a directory.  Setting this user ID (UID) to something
+	  other than "0" will cause all files owned by that UID to be
+	  owned by user root in the initial ramdisk image.
+
+	  If you are not sure, leave it set to "0".
+
+config INITRAMFS_ROOT_GID
+	int "Group ID to map to 0 (group root)"

+	help
+	  This setting is only meaningful if the INITRAMFS_SOURCE is
+	  contains a directory.  Setting this group ID (GID) to something
+	  other than "0" will cause all files owned by that GID to be
