It adds a GNU hash to the vDSO. I don't anticipate any problems, but it's remotely possible that there'a a buggy glibc out there that will object. If that happens, we can deal with it by reverting or by recommending that users set CONFIG_COMPAT_VDSO, depending on how obscure the breakage is. Apparently this gives an impressive speedup loading large programs with some ELF interpreters. Please consider pulling for Linux 4.3.
