Hi,

arm use __NR_sync_file_range2 not __NR_sync_file_range for system call.
the test casecheck __NR_sync_file_range for arm,
So test react "System doesn't support" for arm.
but actually arm use __NR_sync_file_range2 to support the system call.

powerpc is big endian, arm is small endian, so the parameter dealing is 
different.

Thanks,
Lina
