[GIT PULL] A vdso change for 4.3

Hi Ingo,

Here's a trivial vDSO change.. 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.
