Like this:
	/*
	 * New syscall number has to be assigned to regs[2] because
	 * it is loaded from there unconditionally after return from
	 * syscall_trace_enter() invocation.
	 *
	 * Consequently, if the syscall was indirect and nr != __NR_syscall,
	 * then after this assignment the syscall will cease to be indirect.
