    kbuild: sparse needs CF not CHECKFLAGS · a887a07d
    Geert Uytterhoeven authored
    Documentation/sparse.txt tells to use:
    
        make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"
    
    However, this still doesn't enable endian checks. The correct syntax is:
    
        make C=2 CF="-D__CHECK_ENDIAN__"
    
    This documentation bug was introduced by the following commit:
    
        commit 1c7bafe7

    	kbuild: clarify "make C=" build option
    
    	Clarify the use of "make C=" in the top-level Makefile, and fix a
    	typo in the Documentation file.

    This `typo' was not a typo, as `CF' had been introduced much earlier, by:
    
        commit 7b49bb9a

    	[PATCH] kbuild: CF=<arguments> passes arguments to sparse
    
    	Allows to add to sparse arguments without mutilating makefiles - just
    	pass CF=<arguments> and they will be added to CHECKFLAGS.
