Beware that the cpu_to_le64() in tools/perf is bogus, we

When decoding the perf_regs mask in regs_dump__printf(),
we loop through the mask using find_first_bit and find_next_bit functions.
And mask is of type "u64". But "u64" is send as a "unsigned long *" to
lib functions along with sizeof().
While the exisitng code works fine in most of the case, when
9 matches
