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