[PATCH] sysctl: C99 convert arch/ia64/kernel/perfmon and remove ABI breakage

Browse Source 
This convters 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.
