But they do. For ARMv7, smb_mb(), smp_rmb() and smp_wmb() become dmb ish, dmb ish and dmb ishst respectively. This was introduced in: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/arm/include/asm/barrier.h?id=3ea128065ed20d33bd02ff6dab689f88e38000be / Leif _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
