("[PATCH v2 00/30] tcg: Improve atomicity support")

This adds some plumbing to handle an ARM page table corner case.

But first, we need to reorg the page table bits to make room,
and in the process resolve a long-standing FIXME for AdvSIMD.

Richard Henderson (13):
  target/sparc: Use tlb_set_page_full
  accel/tcg: Retain prot flags from tlb_fill
  accel/tcg: Store some tlb flags in CPUTLBEntryFull
  accel/tcg: Honor TLB_DISCARD_WRITE in atomic_mmu_lookup
  softmmu/physmem: Check watchpoints for read+write at once
  accel/tcg: Trigger watchpoints from atomic_mmu_lookup
  accel/tcg: Move TLB_WATCHPOINT to TLB_SLOW_FLAGS_MASK
  target/arm: Support 32-byte alignment in pow2_align
  exec/memattrs: Remove target_tlb_bit*
  accel/tcg: Add tlb_fill_flags to CPUTLBEntryFull
  accel/tcg: Add TLB_CHECK_ALIGNED
  target/arm: Do memory type alignment check when translation disabled
  target/arm: Do memory type alignment check when translation enabled
