 Most Makefiles within the kernel are kbuild Makefiles that use the
 kbuild infrastructure. This chapter introduce the syntax used in the
 kbuild makefiles.
-The preferred name for the kbuild files is 'Kbuild' but 'Makefile' will
-continue to be supported. All new developmen is expected to use the
-Kbuild filename.
+The preferred name for the kbuild files are 'Makefile' but 'Kbuild' can
+be used and if both a 'Makefile' and a 'Kbuild' file exists then the 'Kbuild'
+file will be used.
 
 Section 3.1 "Goal definitions" is a quick intro, further chapters provide
 more details, with real examples.

 	to the target file are prefixed with $(obj), references
 	to prerequisites are referenced with $(src) (because they are not
 	generated files).
+
+--- 3.11 $(CC) support functions
+
+	The kernel may be build with several different versions of
+	$(CC), each supporting a unique set of features and options.
+	kbuild provide basic support to check for valid options for $(CC).
+	$(CC) is useally the gcc compiler, but other alternatives are
+	available.
+
+    as-option
+    	as-option is used to check if $(CC) when used to compile
+	assembler (*.S) files supports the given option. An optional
+	second option may be specified if first option are not supported.
+
+	Example:
+		#arch/sh/Makefile
+		cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),)
+
+	In the above example cflags-y will be assinged the the option
+	-Wa$(comma)-isa=$(isa-y) if it is supported by $(CC).
+	The second argument is optional, and if supplied will be used
+	if first argument is not supported.
+
+    cc-option
+	cc-option is used to check if $(CC) support a given option, and not
+	supported to use an optional second option.
+
+	Example:
+		#arch/i386/Makefile
+		cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586)
+
+	In the above example cflags-y will be assigned the option
+	-march=pentium-mmx if supported by $(CC), otherwise -march-i586.
+	The second argument to cc-option is optional, and if omitted
+	cflags-y will be assigned no value if first option is not supported.
+
+   cc-option-yn
+   	cc-option-yn is used to check if gcc supports a given option
+	and return 'y' if supported, otherwise 'n'.
+
+	Example:
+		#arch/ppc/Makefile
+		biarch := $(call cc-option-yn, -m32)
+		aflags-$(biarch) += -a32
+		cflags-$(biarch) += -m32
+	
+	In the above example $(biarch) is set to y if $(CC) supports the -m32
+	option. When $(biarch) equals to y the expanded variables $(aflags-y)
+	and $(cflags-y) will be assigned the values -a32 and -m32.
+
+    cc-option-align
+	gcc version >= 3.0 shifted type of options used to speify
+	alignment of functions, loops etc. $(cc-option-align) whrn used
+	as prefix to the align options will select the right prefix:
+	gcc < 3.00
+		cc-option-align = -malign
+	gcc >= 3.00
+		cc-option-align = -falign
+	
+	Example:
+		CFLAGS += $(cc-option-align)-functions=4
+
+	In the above example the option -falign-functions=4 is used for
+	gcc >= 3.00. For gcc < 3.00 -malign-functions=4 is used.
+	
+    cc-version
+	cc-version return a numerical version of the $(CC) compiler version.
+	The format is <major><minor> where both are two digits. So for example
+	gcc 3.41 would return 0341.
+	cc-version is useful when a specific $(CC) version is faulty in one
+	area, for example the -mregparm=3 were broken in some gcc version
+	even though the option was accepted by gcc.
+
+	Example:
+		#arch/i386/Makefile
+		cflags-y += $(shell \
+		if [ $(call cc-version) -ge 0300 ] ; then \
+			echo "-mregparm=3"; fi ;)
+
+	In the above example -mregparm=3 is only used for gcc version greater
+	than or equal to gcc 3.0.
+
+    cc-ifversion
+	cc-ifversion test the version of $(CC) and equals last argument if
+	version expression is true.
+
+	Example:
+		#fs/reiserfs/Makefile
+		EXTRA_CFLAGS := $(call cc-ifversion, -lt, 0402, -O1)
+
+	In this example EXTRA_CFLAGS will be assigned the value -O1 if the
+	$(CC) version is less than 4.2.
+	cc-ifversion takes all the shell operators: 
+	-eq, -ne, -lt, -le, -gt, and -ge
+	The third parameter may be a text as in this example, but it may also
+	be an expanded variable or a macro.

+	This works equal for the kernel, a module and even for external
+	modules.
+	Examples (module foo.ko, consist of bar.o, baz.o):
+		make -C $KDIR M=`pwd` bar.lst

 Module versioning is enabled by the CONFIG_MODVERSIONS tag.
 
···
 compared with similar values in the module. If they are not equal then the
 kernel refuses to load the module.
 
-During a kernel build a file named Module.symvers will be generated. This
-file includes the symbol version of all symbols within the kernel. If the 
-Module.symvers file is saved from the last full kernel compile one does not
-have to do a full kernel compile to build a module version's compatible module.
+Module.symvers contains a list of all exported symbols from a kernel build.
 
+--- 7.1 Symbols fron 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 symbols the corresponding CRC value
+	is stored too.
+
+	The syntax of the Module.symvers file is:
+		<CRC>       <Symbol>           <module>
+	Sample:
+		0x2d036834  scsi_remove_host   drivers/scsi/scsi_mod
+
+	For a kernel build without CONFIG_MODVERSIONING enabled the crc
+	would read: 0x00000000
+
+	Module.symvers serve two purposes.
+	1) It list all exported symbols both from vmlinux and all modules
+	2) It list CRC if CONFIG_MODVERSION 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 build this file will be read too.
+	During the MODPOST step a new Module.symvers file will be written
+	containing all exported symbols that was not defined in the kernel.
+	
+--- 7.3 Symbols from another external module
+
+	Sometimes one 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.
+	Two 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', '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)
+			obj-y := foo/ bar/
+
+		Executing:
+			make -C $KDIR M=`pwd`
+
+		will then do the expected and compile both modules with full
+		knowledge on symbols from both modules.
+
+	Use an extra Module.symvers file
+		When an external module is build 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 build.
+		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.
