It's possible that the destination can be shadowed in userspace (as, for example, the perf buffers are now). So we should take care not to leak data that could be inspected by userspace.
Oops, we need to ensure platforms all have zero_bytemask() before we can do this. It's pretty trivial in general, but not all platforms have it now. I'll post a patch to fix this as needed, which should be taken before this patch to avoid git bisect failures. I'll also see about fixing some skew in platforms that are either newer than the patch (h8300) or added word-at-a-time.h since the original patch (powerpc, tile). -- Chris Metcalf, EZChip Semiconductor http://www.ezchip.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
