Prevent Linux kernel from logging segfaults of user processes

["Steve Keller" <keller.steve@gmx.de>]

Since quite a long time the Linux kernel prints log messages about
processes that cause a segmentation fault, but it has not always
been that way (Linux 2.x, maybe also 3.x versions, AFAIR).

On a multi-user system, where users develop & debug software it is
annoying for the admin to see all these messages in dmesg.

So my question is can these messages been turned off, either completely
or for certain (effective or real) user ids, e.g. uid above 1000?
