[PATCH 3.16 125/131] mm/vmstat: Make NR_TLB_REMOTE_FLUSH_RECEIVED available even on UP

[Ben Hutchings]

3.16.59-rc1 review patch.  If anyone has any objections, please let me know.

------------------

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.
