SUMMARY
valgrind memcheck receive SIGBUS on octeon II CPU CN61xx。

STEPS TO REPRODUCE
1. build a valgrind for a cavium octeonII CPU 
./configure --enable-only64bit --target=mips64-octeon-linux-gnu --host=mips64-octeon-linux-gnu --prefix=/usr --program-prefix="" CFLAGS="-march=octeon2 -Werror"
make 
gcc version is 4.7 glibc is 2.16 kernel version is 3.10 valgrind code is 3.14.0
2. try to start a program using valgrind without any param on a cavium board. get a log like this

The below message tells that valgrind version is 3.12.0.
It would be good to try with the latest release (3.14.0) or
even the GIT version.

Sorry， I have not give the right log。  I tried both 3.12 and 3.14, and the log of 3.14 is as following:
