    Subject[PATCH 4/5] perf intel-pt: Packet splitting can happen only on 32-bit
    Date
    Data is copied when the trace is stopped, so packets are never split
    between buffers except when processing if the buffer cannot fit in the
    address space which can only happen on 32-bit systems. Change the logic to
    reflect that.
