Context checking currently requires explicitly passing the -Wcontext option. In a Linux build, this requires passing CF=-Wcontext. Thus, running people running sparse over Linux or other software in the default way will not see context warnings. Change this by enabling -Wcontext. While context checking does generate false positives, due to both missing annotations on kernel functions and insufficiently clever checking in sparse, the context warnings still do provide useful information and help track down real bugs. Furthermore, showing these warnings by default may incite more people to add annotations or enhance sparse. As a last resort, -Wno-context will still work.
