[PATCH] x86: Fix the symbol versions on the 32-bit vDSO

From: Andy Lutomirski
Date: Sat Mar 29 2014 - 16:15:58 EST


The new symbols provide the same API as the 64-bit variants, so they
should have the same symbol version name. This can't break
userspace, since these symbols are new for 32-bit Linux.
