[ARM] 2896/1: Add sys_ipc_wrapper to pass 'fifth' argument on stack
Patch from George G. Davis As pointed out be Matthew Klahn <MKLAHN@motorola.com>, some sys_ipc() call options require six args, e.g. SEMTIMEDOP. This patch adds an ARM sys_ipc_wrapper to save the sys_ipc() 'fifth' arg on the stack. Signed-off-by: George G.
