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 ‘change_pmd_protnuma’:
mm/mprotect.c:120: error: implicit declaration of function ‘set_pmd_at’
mm/memory.c: In function ‘do_pmd_numa_page’:
mm/memory.c:3529: error: implicit declaration of function ‘set_pmd_at’
