  [IA64] Wire up kcmp syscall (2015-10-28 14:22:59 -0700)

----------------------------------------------------------------
Missed adding the kcmp() syscall a long time ago. Now it seems
that it is essential to build systemd.

Thanks.

Tony, this reminds me a comment that you made some time ago, when I
sent to the linux-ia64 patches to add accept4() syscall that was
equally forgotten in it's time.

Here's what you were saying to me by mail on September 1st, 2012:

"Hmmm.  I looked into this a bit further - and found that I hadn't
seen a warning about the missing accept4() system call from
scripts/checksyscalls.sh because it just compares against the x86_32
list - and accept4() isn't there."

Hence my question: Was it also the case for kcmp() syscall? If yes,
what could be done to ensure that such miss at adding syscall can be
avoided in the future?
