Only the memory_barrer one is a bug; the rest improve system-wide
interaction, and would only affect pre-armv6.

Changes for v2:
   * Adjust atomic_mmu_lookup as per laurent.
   * Fix alignment check for arm_kernel_cmpxchg32_helper.

Richard Henderson (3):
  linux-user/arm: Implement __kernel_memory_barrier
  linux-user/arm: Implement __kernel_cmpxchg with host atomics
  linux-user/arm: Implement __kernel_cmpxchg64 with host atomics
