perf_event_open system call support in powerpc

Hello,

 I am new to the powerpc architecture and I am trying to use
perf_event_open() system call for power pc architecture (e500mc) using
2.6.32 kernel distribution. Is this system call number supported for power
pc architecture? If yes, is there something similar to
 arch/x86/kernel/syscall_table_32.S  listing for powerpc that indicates the
number for the above system call?

Thanks in advance for assisting me. Please email me at
