[-- Attachment #1: do-not-allow-prio-below-one-in-cyclictest.patch --]
[-- Type: text/plain, Size: 808 bytes --]

If not in SMP testing mode, the priority may go below 1, if the specified
priority is lower than the number of threads, e.g.
# cyclictest -p2 -t3
T: 0 (21970) P: 2 [..]
T: 1 (21971) P: 1 [..]
T: 2 (21972) P: 0 [..]

Do not allow priority to go below 1.
