[PATCH v2 0/3] linux-user/arm: Improvements for commpage atomics

[Richard Henderson]

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.
