Daniel,

sorry folk are seing you patches with crap commit logs. The
justification should be made clearer: we're moving sysctls out of
kernel/sysctl.c as its a mess. I already moved all filesystem sysctls
out. And with time the goal is to move all sysctls out to their own
susbsystem/actual user.

kernel/sysctl.c has grown to an insane mess and its easy to run
into conflicts with it. The effort to move them out is part of this.

The commit logs should not suck though...
