[Bug general/4704] New: kernel test: VDSO permissions in /proc/PID/maps


Backtraces were corrupted on some kernel versions as the VDSO memory area being
used for the return from the kernel had unset permissions (--- instead of r-x).

It affected the GDB gcore command and IIRC Frysk also respected these broken
permissions and failed in such cases.

The kernel Bug has been tracked at least by:
