xtensa: userspace: align stack before calling syscall handler We stuff the 7th argument into stack by moving the stack pointer before calling syscall handler. The Xtensa ABI says stack must be 16-byte aligned. So instead of moving stack pointer 4 bytes, we move 16 bytes (assuming stack has been aligned so far).
