From: Changbin Du <changbin.du@intel.com>
The token '__print_array' is to print the array in hex format, but not
decimal numbers. The implementation of __print_array in kernel side is:
__print_array()->trace_print_array_seq()
This patch align the perf's behavior with kernel so we have a consistent
event format.

Look ok, i.e. makes the userspace formatting do what the equivalent
kernel code does, Rostedt, Ack?

Thanks for sending this to me. I'll see how it affects trace-cmd, and
let you know.
