CONFIG_PARAVIRT defines set_pmd_at only for CONFIG_TRANSPARENT_HUGEPAGE
which leads to the following compile errors when randconfig selected
CONFIG_NUMA_BALANCING && CONFIG_PARAVIRT && !CONFIG_TRANSPARENT_HUGEPAGE:

mm/mprotect.c: In function a??change_pmd_protnumaa??:
mm/mprotect.c:120: error: implicit declaration of function a??set_pmd_ata??

mm/memory.c: In function a??do_pmd_numa_pagea??:
mm/memory.c:3529: error: implicit declaration of function a??set_pmd_ata??
