This patch wires up the new copy_file_range syscall on AVR32. On AVR32, all parameters beyond the 5th are passed on the stack. System calls don't use the stack -- they borrow a callee-saved register instead. This means that syscalls that take 6 parameters must be called through a stub that pushes the last parameter on the stack. Signed-off-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no>
