x86: restore vsyscall64 prochandler
a recent fix: commit ce28b9864b853803320c3f1d8de1b81aa4120b14 Author: Thomas Gleixner <tglx@linutronix.de> Date: Wed Feb 20 23:57:30 2008 +0100 x86: fix vsyscall wreckage removed the broken /kernel/vsyscall64 handler completely. This triggers the following debug check: sysctl table check failed: /kernel/vsyscall64 No proc_handler Restore the sane part of the proc handler.
