That one causes:

    mm/percpu.c: In function ‘setup_per_cpu_areas’:
    mm/percpu.c:1877: error: implicit declaration of function ‘kmemleak_free’
    make[1]: *** [mm/percpu.o] Error 1
    make: *** [mm] Error 2

Trivial fix, works for me: Add

    #include <linux/kmemleak.h>

to mm/percpu.c. FWIW, upstream did this in in f528f0b but I cannot
tell whether that commit is in any way of interest for 3.0.x.
