Subject: mm/vmstat: Make NR_TLB_REMOTE_FLUSH_RECEIVED available even on UP
From: Andy Lutomirski <luto@xxxxxxxxxx>
commit 5dd0b16cdaff9b94da06074d5888b03235c0bf17 upstream.
This fixes CONFIG_SMP=n, CONFIG_DEBUG_TLBFLUSH=y without introducing
further #ifdef soup. Caught by a Kbuild bot randconfig build.
