I am not sure if I should merge above patch into original one. If I
merge it with another patch I send in 13, April, The overall patch is
as follows. I could resend the following patch to this thread if
needed:

 From b0a74395cbf18643f3f5b410be425df85d8d68d1 Mon Sep 17 00:00:00 2001
From: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
Date: Wed, 6 Apr 2016 01:08:46 +0300
Subject: [PATCH] arm64:ilp32: add vdso-ilp32 and use for signal return

ILP32 VDSO exports next symbols:
  __kernel_rt_sigreturn;
  __kernel_gettimeofday;
  __kernel_clock_gettime;
  __kernel_clock_getres;

What shared object to use, kernel selects depending on result of
is_ilp32_compat_task() in arch/arm64/kernel/vdso.c, so it substitutes
correct pages and spec.

Adjusted to move the move data page before code pages in sync with
commit 601255ae3c98fdeeee3a8bb4696425e4f868b4f1

Care must be taken when we update time to user space for ilp32.
Because the size of time struct(timeval, timespec) is different from
lp64.
