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.
