selftests/x86: Add vDSO mremap() test
Should print this on vDSO remapping success (on new kernels):
[root@localhost ~]# ./test_mremap_vdso_32
AT_SYSINFO_EHDR is 0xf773f000
[NOTE] Moving vDSO: [f773f000, f7740000] -> [a000000, a001000]
[OK]
Or print that mremap() for vDSOs is unsupported:
[root@localhost ~]# ./test_mremap_vdso_32
AT_SYSINFO_EHDR is 0xf773c000
[NOTE] Moving vDSO: [0xf773c000, 0xf773d000] -> [0xf7737000, 0xf7738000]
[FAIL] mremap() of the vDSO does not work on this kernel!
