Subject: mm/vmstat.c: fix /proc/vmstat format for CONFIG_DEBUG_TLBFLUSH=y CONFIG_SMP=n
58bc4c34d249 ("mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly") depends
on skipping vmstat entries with empty name introduced in 7aaf77272358
("mm: don't show nr_indirectly_reclaimable in /proc/vmstat") but reverted
in b29940c1abd7 ("mm: rename and change semantics of
nr_indirectly_reclaimable_bytes").
So skipping no longer works and /proc/vmstat has misformatted lines " 0".
This patch simply shows debug counters "nr_tlb_remote_*" for UP.
