72b7a9e56b powerpc/syscall: Use is_compat_task() 
Instead of hard comparing task flags with _TIF_32BIT, use
is_compat_task(). The advantage is that it returns 0 on PPC32
allthough _TIF_32BIT is always set.

ab1a517d55 powerpc/syscall: Rename syscall_64.c into interrupt.c 
syscall_64.c will be reused almost as is for PPC32.

As this file also contains functions to handle other types
of interrupts rename it interrupt.c
