Subject[PATCH 29/59] sysctl: C99 convert arch/ia64/kernel/perfmon and remove ABI breakage
Date
From: Eric W. Biederman <ebiederm@xmission.com> - unquoted

This convers the sysctl ctl_tables to use C99 initializers.
While I was looking at it I discovered it was using a portion of
the sysctl binary addresses space under CTL_KERN KERN_OSTYPE
which was completely inappropriate. So I completely removed
all of the sysctl binary names, to remove and avoid the ABI conflict.
