1763fa5f62 s390, s390x: fix printing of syscalls unknown to the kernel
On s390/s390x, syscalls with NR up to 255 can be implemented
directly using "svc NR", for NR >= 256 "svc 0" with %r1=NR is used.
The latter method is allowed for NR < 256, too.

When the syscall number specified directly or indirectly is recognized
by the kernel, i.e. it is less than its NR_syscalls value, it is stored
in %r2 and is available to arch_get_scno via s390_regset.gprs[2].
For syscall numbers >= NR_syscalls this register is set to 0,
but %r1 remains unchanged and could be used by arch_get_scno
via s390_regset.gprs[1] to decide what the syscall number is.

* linux/s390/get_scno.c (arch_get_scno): If s390_regset.gprs[2] is zero,
take syscall number from s390_regset.gprs[1].
* NEWS: Mention this fix.

This fixes Debian bug #485979 and Fedora bug #1298294.

be1cb92c72 Fix printing of 32-bit times syscall return value on 64-bit architectures

when current personality is 32-bit, print 32-bit return code.
* NEWS: Mention this fix.

e53bf23f1c Optionally produce stats on syscall latency
Time spent in system time is not useful where a syscall depends on some
non-CPU resource, eg. typically open() or stat() to a network drive.

This patch adds a new flag (-w) to produce a summary of the time
difference between beginning and end of the system call (ie. latency)

This functionality has been useful to profile slow processes that
are not CPU-bound.
