sparc64: Allocate sufficient stack space in ftrace stubs.
128 bytes is sufficient for the register window save area, but the calling conventions allow the callee to save up to 6 incoming argument registers into the stack frame after the register window save area. This means a minimal stack frame is 176 bytes (128 + (6 * 8)). This fixes random crashes when using the function tracer. Reported-by:Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by:
