Subject: [RFC PATCH 0/2] minor mmu_gather patches

These are split from some patches I posted a while back, I was going
to take a look and revive the series again after your fixes go in,
but having another look, it may be that your "[PATCH 3/4] mm/tlb,
x86/mm: Support invalidating TLB caches for RCU_TABLE_FREE" becomes
easier after my patch 1.

And I'm not convinced patch 2 is not a real bug at least for ARM64,
so it may be possible to squeeze it in if it's reviewed very
carefully (I need to actually reproduce and trace it).

So not signed off by yet, but if you think it might be worth doing
these with your changes, it could be a slightly cleaner end result?

Thanks,
Nick

Nicholas Piggin (2):
  mm: move tlb_table_flush to tlb_flush_mmu_free
  mm: mmu_notifier fix for tlb_end_vma
