mm: move tlb_table_flush to tlb_flush_mmu_free
commit db7ddef301128dad394f1c0f77027f86ee9a4edb upstream. There is no need to call this from tlb_flush_mmu_tlbonly, it logically belongs with tlb_flush_mmu_free. This makes future fixes simpler. [ This was originally done to allow code consolidation for the mmu_notifier fix, but it also ends up helping simplify the HAVE_RCU_TABLE_INVALIDATE fix. - Linus ] Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Acked-by: Will Deacon <will.deacon@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> [bwh: Backported to 3.16: adjust context] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
