Top posting.. :(

It will not recompile if the .o files are already there and .c files
have not been modified. So if you want to recompile all files do make clean
or much better make distclean. make distclean will clean everything even
your .config file also. But usually when I am working or checking patches
for staging I will just do make clean M=drivers/staging , so it will just
clean staging and now when you make again it will compile all files in
staging which are in your .config.
With sparse if you use C=2 then it will recompile even .o files are
there, but with C=1 the default behaviour of not compiling will take
effect.
