  kbuild: fix the warning when running make tags
  kconfig: strip 'CONFIG_' automatically in kernel configuration search
  kbuild: use POSIX BRE in headers install target
  Whitelist references from __dbe_table to .init
  modpost white list pattern adjustment
  kbuild: do section mismatch check on full vmlinux
  kbuild: whitelist references from variables named _timer to .init.text
  kbuild: remove hardcoded _logo names from modpost
  kbuild: remove hardcoded apic_es7000 from modpost
  kbuild: warn about references from .init.text to .exit.text
  kbuild: consolidate section checks
  kbuild: refactor code in modpost to improve maintainability
  kbuild: ignore section mismatch warnings originating from .note section

 	The third parameter may be a text as in this example, but it may also
 	be an expanded variable or a macro.
 
+    cc-fullversion
+	cc-fullversion is useful when the exact version of gcc is needed.
+	One typical use-case is when a specific GCC version is broken.
+	cc-fullversion points out a more specific version than cc-version does.
+
+	Example:
+		#arch/powerpc/Makefile
+		$(Q)if test "$(call cc-fullversion)" = "040200" ; then \
+			echo -n '*** GCC-4.2.0 cannot compile the 64-bit powerpc ' ; \
+			false ; \
+		fi
+
+	In this example for a specific GCC version the build will error out explaining
+	to the user why it stops.
