RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 1 Mark Wielaard 2019-03-04 15:34:44 UTC 
ppc64le syscall number 131 is quotactl.
This looks like a generic linux syscall that is just not hooked up for ppc64le.

Totally untested patch:

Comment 2 Mark Wielaard 2019-03-04 20:05:08 UTC 
That patch seems to do the trick. See upstream bug https://bugs.kde.org/show_bug.cgi?id=405079

That patch is now upstream, in the fedora package (for f30 & rawhide) and the copr packages:
https://copr.fedorainfracloud.org/coprs/mjw/valgrind-3.14.0/
Comment 3 Mark Wielaard 2019-04-20 20:19:42 UTC 
This fix has been integrated upstream and is part of the 3.15.0 upstream release.
Comment 6 Alexandra Petlanová Hájková 2019-06-18 11:45:41 UTC 
I verified valgrind doesn't support the quotactl sycall on ppcc64le for valgrind-3.14.0-11 and does support it for valgrind-3.15.0-2.
