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. This patch adds a stub for sync_file_range syscall on AVR32 architecture. Tested with uClibc snapshot. Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
