Thanks for the patch.
More fix lines should be added:
Fixes: 17d5fa0fa90d ("eal/arm: add atomic operations for ARMv7")
Fixes: d708f01b7102 ("eal/arm: add atomic operations for ARMv8")
Fixes: 2173f3333b61 ("mcslock: add MCS queued lock implementation")
Fixes: 7860c3965483 ("eal/arm: add spinlock operations for ARM")
Fixes: ca49b92079df ("ticketlock: enable generic ticketlock on all arch")

With the change:
