#     powerpc: Wire up io_pgetevents
#     
#     Wire up io_pgetevents system call on powerpc.
#     
#     io_pgetevents is a new syscall to read asynchronous I/O events from the
#     completion queue.
#     
#     Tested with libaio branch aio-poll[1] and the io_pgetevents test (#22) passed
#     on both ppc64 LE and BE modes.
