x86: Remove unnecessary compile flag tweaks for vsyscall code
As of commit 98d0ac38ca7b1b7a552c9a2359174ff84decb600 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.
