In usr/src/uts/common/disp/cpupart.c, cpupart_create() allocates a buffer and assigns it to the cp_lgrploads member of a cpupart_t struct:

pp->cp_nlgrploads = lgrp_plat_max_lgrps();
    pp->cp_lgrploads = kmem_zalloc(sizeof (lpl_t) * pp->cp_nlgrploads,
        KM_SLEEP);
The function then goes on to call cpupart_lpl_initialize(), which allocates an identical buffer and assigns it to the same field, leaking the original buffer:

sz = cp->cp_nlgrploads = lgrp_plat_max_lgrps();
    cp->cp_lgrploads = kmem_zalloc(sizeof (lpl_t) * sz, KM_SLEEP);
We should be able to just remove the initial allocation.
