As such, we need to ensure the variable holding the value of the branch stack filters is also u64 otherwise we may lose bits in the future. Note also that the bogus definition of the field in perf_record_opts caused problems on big-endian PPC systems. Thanks to Anshuman Khandual for tracking the problem on PPC.
