powerpc/powernv/npu: Use flush_all_mm() instead of flush_tlb_mm()
With the optimisations introduced by commit a46cc7a908 ("powerpc/mm/radix: Improve TLB/PWC flushes"), flush_tlb_mm() no longer flushes the page walk cache with radix. Switch to using flush_all_mm() to ensure the pwc and tlb are properly flushed on the nmmu. Signed-off-by: Alistair Popple <alistair@popple.id.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
