The patch titled Subject: mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly has been removed from the -mm tree. Its filename was mm-vmstat-skip-nr_tlb_remote_flush-properly.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------ From: Jann Horn jannh@google.com Subject: mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly
5dd0b16cdaff ("mm/vmstat: Make NR_TLB_REMOTE_FLUSH_RECEIVED available even on UP") made the availability of the NR_TLB_REMOTE_FLUSH* counters inside the kernel unconditional to reduce #ifdef soup, but (either to avoid showing dummy zero counters to userspace, or because that code was missed) didn't update the vmstat_array, meaning that all following counters would be shown with incorrect values.
This only affects kernel builds with CONFIG_VM_EVENT_COUNTERS=y && CONFIG_DEBUG_TLBFLUSH=y && CONFIG_SMP=n.
