commit 562f507e062ea74999eb0c73d156b81f46fe9257

    headers: untangle kmemleak.h from mm.h
    
    Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious
    reason. It looks like it's only a convenience, so remove kmemleak.h
    from slab.h and add <linux/kmemleak.h> to any users of kmemleak_*
    that don't already #include it.
    Also remove <linux/kmemleak.h> from source files that do not use it.
    
    This is tested on i386 allmodconfig and x86_64 allmodconfig. It
    would be good to run it through the 0day bot for other $ARCHes.
    I have neither the horsepower nor the storage space for the other
    $ARCHes.
    
    Update: This patch has been extensively build-tested by both the 0day
    bot & kisskb/ozlabs build farms. Both of them reported 2 build failures
    for which patches are included here (in v2).
    
    [slab.h is the second most used header file after module.h; kernel.h
    is right there with slab.h. There could be some minor error in the
    counting due to some #includes having comments after them and I
    didn't combine all of those.]
