Description Mark Wielaard 2016-05-30 16:17:03 UTC 
Running systemd under nspawn with valgrind needs these system calls.

Reproducible: Always




Probably as simple as this (untested) patch:

Comment 1 Mark Wielaard 2016-05-30 20:16:29 UTC 
Tested on ppc64 running some simple programs using the system calls.
Patch applied as valgrind svn r15888.
