[PATCH] sysctl: Allow /proc/sys without sys_sysctl
Since sys_sysctl is deprecated start allow it to be compiled out. This should catch any remaining user space code that cares, and paves the way for further sysctl cleanups. [firstname.lastname@example.org: If sys_sysctl() is not compiled-in, emit a warning] Signed-off-by: Eric W.

- The sysctl interface provides a means of dynamically changing
- certain kernel parameters and variables on the fly without requiring
- a recompile of the kernel or reboot of the system. The primary
- interface consists of a system call, but if you say Y to "/proc
- file system support", a tree of modifiable sysctl entries will be
- generated beneath the /proc/sys directory. They are explained in the
- files in <file:Documentation/sysctl/>. Note that enabling this
- option will enlarge the kernel by at least 8 KB.
- As it is generally a good thing, you should say Y here unless
- building a kernel for install/rescue disks or your system is very
- limited in memory.
+ Enable the deprecated sysctl system call. sys_sysctl uses
+ binary paths that have been found to be a major pain to maintain
+ and use. The interface in /proc/sys is now the primary and what
+ everyone uses.
+ Nothing has been using the binary sysctl interface for some time
+ time now so nothing should break if you disable sysctl syscall
+ support, and you kernel will get marginally smaller.
+ Unless you have an application that uses the sys_syscall interface
+ you should probably say N here.
