Peter Zijlstra e7fd28a706 asm-generic/tlb, arch: Provide generic VIPT cache flush
The one obvious thing SH and ARM want is a sensible default for
tlb_start_vma(). (also: https://lkml.org/lkml/2004/1/15/6 )

Avoid all VIPT architectures providing their own tlb_start_vma()
implementation and rely on architectures to provide a no-op
flush_cache_range() when it is not relevant.

This patch makes tlb_start_vma() default to flush_cache_range(), which
should be right and sufficient. The only exceptions that I found where
(oddly):

  - m68k-mmu
  - sparc64
  - unicore

Those architectures appear to have flush_cache_range(), but their
current tlb_start_vma() does not call it.

No change in behavior intended.
