x86: Remove unnecessary compile flag tweaks for vsyscall code
As of commit 98d0ac38ca
Author: Andy Lutomirski <luto@mit.edu>
Date: Thu Jul 14 06:47:22 2011 -0400
x86-64: Move vread_tsc and vread_hpet into the vDSO
user code no longer directly calls into code in arch/x86/kernel/, so
we don't need compile flag hacks to make it safe. All vdso code is
in the vdso directory now.
