-=== 5. Include files
+=== 4. Include Files
 
-Include files are a necessity when a .c file uses something from other .c
-files (not strictly in the sense of C, but if good programming practice is
-used). Any module that consists of more than one .c file will have a .h file
-for one of the .c files.
+Within the kernel, header files are kept in standard locations
+according to the following rule:
 
-- If the .h file only describes a module internal interface, then the .h file
-  shall be placed in the same directory as the .c files.
-- If the .h files describe an interface used by other parts of the kernel
-  located in different directories, the .h files shall be located in
-  include/linux/ or other include/ directories as appropriate.
+	* If the header file only describes the internal interface of a
+	  module, then the file is placed in the same directory as the
+	  source files.
+	* If the header file describes an interface used by other parts
+	  of the kernel that are located in different directories, then
+	  the file is placed in include/linux/.
 
-One exception for this rule is larger subsystems that have their own directory
-under include/ such as include/scsi. Another exception is arch-specific
-.h files which are located under include/asm-$(ARCH)/*.
+	  NOTE: There are two notable exceptions to this rule: larger
+	  subsystems have their own directory under include/, such as
+	  include/scsi; and architecture specific headers are located
+	  under arch/$(ARCH)/include/.
 
-External modules have a tendency to locate include files in a separate include/
-directory and therefore need to deal with this in their kbuild file.
+--- 4.1 Kernel Includes
 
---- 5.1 How to include files from the kernel include dir
-
-	When a module needs to include a file from include/linux/, then one
-	just uses:
+	To include a header file located under include/linux/, simply
+	use:
 
 		#include <linux/modules.h>
 
-	kbuild will make sure to add options to gcc so the relevant
-	directories are searched.
-	Likewise for .h files placed in the same directory as the .c file.
-
-		#include "8123_if.h"
-
-	will do the job.
+	kbuild will add options to "gcc" so the relevant directories
+	are searched.
 
---- 5.2 External modules using an include/ dir
+--- 4.2 Single Subdirectory
 
-	External modules often locate their .h files in a separate include/
-	directory although this is not usual kernel style. When an external
-	module uses an include/ dir then kbuild needs to be told so.
-	The trick here is to use either EXTRA_CFLAGS (take effect for all .c
-	files) or CFLAGS_$F.o (take effect only for a single file).
+	External modules tend to place header files in a separate
+	include/ directory where their source is located, although this
+	is not the usual kernel style. To inform kbuild of the
+	directory use either ccflags-y or CFLAGS_<filename>.o.
 
-	In our example, if we move 8123_if.h to a subdirectory named include/
-	the resulting Kbuild file would look like:
+	Using the example from section 3, if we moved 8123_if.h to a
+	subdirectory named include, the resulting kbuild file would
+	look like:
 
 		--> filename: Kbuild
-		obj-m  := 8123.o
+		obj-m := 8123.o
 
-		EXTRA_CFLAGS := -Iinclude
+		ccflags-y := -Iinclude
 		8123-y := 8123_if.o 8123_pci.o 8123_bin.o
 
-	Note that in the assignment there is no space between -I and the path.
-	This is a kbuild limitation:  there must be no space present.
-
---- 5.3 External modules using several directories
+	Note that in the assignment there is no space between -I and
+	the path. This is a limitation of kbuild: there must be no
+	space present.
 
-	If an external module does not follow the usual kernel style, but
-	decides to spread files over several directories, then kbuild can
-	handle this too.
+--- 4.3 Several Subdirectories
 
+	kbuild can handle files that are spread over several directories.
 	Consider the following example:
 
-	|
-	+- src/complex_main.c
-	|   +- hal/hardwareif.c
-	|   +- hal/include/hardwareif.h
-	+- include/complex.h
-
-	To build a single module named complex.ko, we then need the following
+	.
+	|__ src
+	|   |__ complex_main.c
+	|   |__ hal
+	|	|__ hardwareif.c
+	|	|__ include
+	|	    |__ hardwareif.h
+	|__ include
+	    |__ complex.h
+
+	To build the module complex.ko, we then need the following
 	kbuild file:
 
-	Kbuild:
+		--> filename: Kbuild
 		obj-m := complex.o
 		complex-y := src/complex_main.o
 		complex-y += src/hal/hardwareif.o
 
-		EXTRA_CFLAGS := -I$(src)/include
-		EXTRA_CFLAGS += -I$(src)src/hal/include
+		ccflags-y := -I$(src)/include
+		ccflags-y += -I$(src)/src/hal/include
 
+	As you can see, kbuild knows how to handle object files located
+	in other directories. The trick is to specify the directory
+	relative to the kbuild file's location. That being said, this
+	is NOT recommended practice.
 
-	kbuild knows how to handle .o files located in another directory -
-	although this is NOT recommended practice. The syntax is to specify
-	the directory relative to the directory where the Kbuild file is
-	located.
+	For the header files, kbuild must be explicitly told where to
+	look. When kbuild executes, the current directory is always the
+	root of the kernel tree (the argument to "-C") and therefore an
+	absolute path is needed. $(src) provides the absolute path by
+	pointing to the directory where the currently executing kbuild
+	file is located.
 
-	To find the .h files, we have to explicitly tell kbuild where to look
-	for the .h files. When kbuild executes, the current directory is always
-	the root of the kernel tree (argument to -C) and therefore we have to
-	tell kbuild how to find the .h files using absolute paths.
-	$(src) will specify the absolute path to the directory where the
-	Kbuild file are located when being build as an external module.
-	Therefore -I$(src)/ is used to point out the directory of the Kbuild
-	file and any additional path are just appended.

-=== 7. Module versioning & Module.symvers
+=== 6. Module Versioning
 
-Module versioning is enabled by the CONFIG_MODVERSIONS tag.
+Module versioning is enabled by the CONFIG_MODVERSIONS tag, and is used
+as a simple ABI consistency check. A CRC value of the full prototype
+for an exported symbol is created. When a module is loaded/used, the
+CRC values contained in the kernel are compared with similar values in
+the module; if they are not equal, the kernel refuses to load the
+module.

+Module.symvers contains a list of all exported symbols from a kernel

---- 7.1 Symbols from the kernel (vmlinux + modules)

+	During a kernel build, a file named Module.symvers will be
+	generated. Module.symvers contains all exported symbols from
+	the kernel and compiled modules. For each symbol, the
+	corresponding CRC value is also stored.
 
 	The syntax of the Module.symvers file is:
-		<CRC>       <Symbol>           <module>
-	Sample:
+		<CRC>	    <Symbol>	       <module>
+
 		0x2d036834  scsi_remove_host   drivers/scsi/scsi_mod

+	For a kernel build without CONFIG_MODVERSIONS enabled, the CRC
+	would read 0x00000000.
 
 	Module.symvers serves two purposes:
-	1) It lists all exported symbols both from vmlinux and all modules
-	2) It lists the CRC if CONFIG_MODVERSIONS is enabled
-
---- 7.2 Symbols and external modules
-
-	When building an external module, the build system needs access to
-	the symbols from the kernel to check if all external symbols are
-	defined. This is done in the MODPOST step and to obtain all
-	symbols, modpost reads Module.symvers from the kernel.
-	If a Module.symvers file is present in the directory where
-	the external module is being built, this file will be read too.
-	During the MODPOST step, a new Module.symvers file will be written
-	containing all exported symbols that were not defined in the kernel.
-
---- 7.3 Symbols from another external module
-
-	Sometimes, an external module uses exported symbols from another
-	external module. Kbuild needs to have full knowledge on all symbols
-	to avoid spitting out warnings about undefined symbols.
-	Three solutions exist to let kbuild know all symbols of more than
-	one external module.
-	The method with a top-level kbuild file is recommended but may be
-	impractical in certain situations.
-
-	Use a top-level Kbuild file
-		If you have two modules: 'foo' and 'bar', and 'foo' needs
-		symbols from 'bar', then one can use a common top-level kbuild
-		file so both modules are compiled in same build.
-
-		Consider following directory layout:
-		./foo/ <= contains the foo module
-		./bar/ <= contains the bar module
-		The top-level Kbuild file would then look like:
-
-		#./Kbuild: (this file may also be named Makefile)
+	1) It lists all exported symbols from vmlinux and all modules.
+	2) It lists the CRC if CONFIG_MODVERSIONS is enabled.
+
+--- 6.2 Symbols and External Modules
+
+	When building an external module, the build system needs access
+	to the symbols from the kernel to check if all external symbols
+	are defined. This is done in the MODPOST step. modpost obtains
+	the symbols by reading Module.symvers from the kernel source
+	tree. If a Module.symvers file is present in the directory
+	where the external module is being built, this file will be
+	read too. During the MODPOST step, a new Module.symvers file
+	will be written containing all exported symbols that were not
+	defined in the kernel.
+
+--- 6.3 Symbols From Another External Module
+
+	Sometimes, an external module uses exported symbols from
+	another external module. kbuild needs to have full knowledge of
+	all symbols to avoid spitting out warnings about undefined
+	symbols. Three solutions exist for this situation.
+
+	NOTE: The method with a top-level kbuild file is recommended
+	but may be impractical in certain situations.
+
+	Use a top-level kbuild file
+		If you have two modules, foo.ko and bar.ko, where
+		foo.ko needs symbols from bar.ko, then you can use a
+		common top-level kbuild file so both modules are
+		compiled in the same build. Consider following
+		directory layout:
+
+		./foo/ <= contains foo.ko
+		./bar/ <= contains bar.ko
+
+		The top-level kbuild file would then look like:
+
+		#./Kbuild (or ./Makefile):
 			obj-y := foo/ bar/
 
-		Executing:
-			make -C $KDIR M=`pwd`
+		And executing:
+			$ make -C $KDIR M=$PWD
 
-		will then do the expected and compile both modules with full
-		knowledge on symbols from both modules.
+		Will then do the expected and compile both modules with
+		full knowledge of symbols from either module.
 
 	Use an extra Module.symvers file
-		When an external module is built, a Module.symvers file is
-		generated containing all exported symbols which are not
-		defined in the kernel.
-		To get access to symbols from module 'bar', one can copy the
-		Module.symvers file from the compilation of the 'bar' module
-		to the directory where the 'foo' module is built.
-		During the module build, kbuild will read the Module.symvers
-		file in the directory of the external module and when the
-		build is finished, a new Module.symvers file is created
-		containing the sum of all symbols defined and not part of the
-		kernel.
-
-	Use make variable KBUILD_EXTRA_SYMBOLS in the Makefile
-		If it is impractical to copy Module.symvers from another
-		module, you can assign a space separated list of files to
-		KBUILD_EXTRA_SYMBOLS in your Makfile. These files will be
-		loaded by modpost during the initialisation of its symbol
-		tables.
