This is not a regression as this is a new testcase which runs only on 32-bit systems (i386 and powerpc). This test was added by ltp commit 6feed808040a86c54b7ab2dd3839fefd819a42cc (Add set_mempolicy05, CVE-2017-7616).

The commit sha1 (cf01fb9985e8deb25ccf0ea54d916b8871ae0e62 - mm/mempolicy.c: fix error handling in set_mempolicy and mbind.) which fixes this CVE according to https://ubuntu.com/security/CVE-2017-7616, was applied upstream for v4.11-rc6, so both focal/linux and bionic/linux supposedly contain the fix.
