Subject: sysctl: sn: remove sysctl ABI BREAKAGE
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
By not using the enumeration in sysctl.h (or even understanding it) the SN
platform placed their arch specific xpc directory on top of CTL_KERN and only
because they didn't have 4 entries in their xpc directory got lucky and didn't
break glibc.
This is totally irresponsible. So this patch entirely removes sys_sysctl
support from their sysctl code. Hopefully they don't have ascii name
conflicts as well.
And now that they have no ABI numbers add them to the end instead of the
sysctl list instead of the head so nothing else will be overridden.
