Correct decoding of readahead and fadvice64(_64) on PowerPC

Browse Source 
* file.c (sys_readahead): Align 64bit argument.  Handle PowerPC64
like other 64bit architectures.
(sys_fadvise64): Likewise.
(sys_fadvise64_64): Handle PowerPC like ARM.
* linux/powerpc/syscallent.h (sys_readahead): Account for 64bit
argument alignment on PowerPC32.
