Subject: [PATCH 0/3] linux-user/arm: Improvements for commpage atomics
Date: Sun, 13 Mar 2022 21:43:02 -0700	[thread overview]
Message-ID: <20220314044305.138794-1-richard.henderson@linaro.org> (raw)

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

  linux-user/arm: Implement __kernel_memory_barrier
  linux-user/arm: Implement __kernel_cmpxchg with host atomics
