Please explain what is the issue.

No need to Cc stable when fixing a bug which is not in a major release.

Olivier reported an issue this morning, that my commit was breaking 
the build of one of our external module:

make[5]: /path/to/ext-module//path/to/ext-module/Makefile: No such file or directory                                                                                                                      
make[5]: *** No rule to make target '/path/to/ext-module//path/to/ext-module/Makefile'.  Stop.                                                                                                            

The reason is that entries in $(MAKEFILE_LIST) can be absolute.

Marko.

I know that :)
I was asking to update the commit message in a v2 actually.

[PATCH v2] mk: fix external build failure

[Marko Kovacevic]

Code commit for 'make -f' support, breaks the build in cases where
entries in $(MAKEFILE_LIST) are absolute paths. This commit uses
notdir and firstword to ensure that only the local filename is used.

Sorry for the confusion.
In this case, Cc stable is needed because it fixes a fix of a bug
seen with previous releases.
