Hi,

git bisect came up with this:

4d14a459857bd151ecbd14bcd37b4628da00792b is the first bad commit
commit 4d14a459857bd151ecbd14bcd37b4628da00792b
Author: David S. Miller <davem@xxxxxxxxxxxxx>
Date:   Thu Dec 10 23:32:10 2009 -0800

    sparc: Stop trying to be so fancy and use __builtin_{memcpy,memset}()

    This mirrors commit ff60fab71bb3b4fdbf8caf57ff3739ffd0887396
    (x86: Use __builtin_memset and __builtin_memcpy for memset/memcpy)

    Signed-off-by: David S. Miller <davem@xxxxxxxxxxxxx>
