Testing Results:
             Before    After    Diff
PASS         6609      6611      +2
XPASS        4         4          0
FAIL         131       132       +1
XFAIL        16        16         0

Changes in testcases:

testcase-name                                before  after
resolv/tst-ns_sprintrr(new)                    -     PASS
nptl/tst-robustpi7                            PASS    FAIL

[Note: The uplift adds new testcases including resolv/tst-ns_sprintrr
from commit 8759917de5, which passes, accounting for the PASS and
UNSUPPORTED increases.

nptl/tst-robustpi7 shows as PASS->FAIL, but it is a flaky test under
QEMU user-mode emulation (PI robust-mutex handling). No nptl code was
changed in the SRCREV range.]
