  "message": "[S390] fix system call parameter functions.\n\nsyscall_get_nr() currently returns a valid result only if the call\nchain of the traced process includes do_syscall_trace_enter(). But\ncollect_syscall() can be called for any sleeping task, the result of\nsyscall_get_nr() in general is completely bogus.\n\nTo make syscall_get_nr() work for any sleeping task the traps field\nin pt_regs is replace with svcnr - the system call number the process\nis executing. If svcnr \u003d\u003d 0 the process is not on a system call path.\n\nThe syscall_get_arguments and syscall_set_arguments use regs-\u003egprs[2]\nfor the first system call parameter. This is incorrect since gprs[2]\nmay have been overwritten with the system call number if the call\nchain includes do_syscall_trace_enter. Use regs-\u003eorig_gprs2 instead.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n",
