[PATCH 04/18] sysctl extern cleanup - binfmts

[PATCH 04/18] sysctl extern cleanup - binfmts

[Dave Young]

Extern declarations in sysctl.c should be move to their own head file,
and then include them in relavant .c files.

Move core_uses_pid/core_pattern/core_pipe_limit extern declarations
to linux/binfmts.h
suid_dumpable is declared in binfmts.h already.
