[OK]
Or segfault if landing was bad (before patches):
[root@localhost ~]# ./test_mremap_vdso_32
AT_SYSINFO_EHDR is 0xf774f000
[NOTE] Moving vDSO: [f774f000, f7750000] -> [a000000, a001000]
Segmentation fault (core dumped)
Can the segfault be caught and recovered from, to print a proper failure message?
Will add segfault handler, thanks.
