Thank you for the report!
This was introduced in my upstream commit b6e47f3c11c1 ("ARM: 9109/1: oabi-compat: add epoll_pwait handler") and fixed in the immediately following 249dbe74d3c4 ("ARM: 9108/1: oabi-compat: rework epoll_wait/epoll_pwait emulation").
Only the first patch got backported to stable-rc, so it's broken there. If anyone thinks we want to keep the epoll_pwait emulation in stable, I can do a backport, but I would just drop that commit from all stable kernels.
