Ingo said that arches that cannot do cmpxchg in hardware should provide spinlock-based version.
That doesn't make any sense.
If cmpxchg cannot work with user bits of memory, like cmpxchg is supposed to, it's really a crutch more than anything else.
F.e. people will think that such systems can support DRM correctly, they absolutely cannot. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
