 I've just committed two more futex fixes, one affecting the semantics
 of FUTEX_WAKE_OP (which appeared in the ktrace for PR kern/58677
 though not with parameters that are affected) and another affecting
 the timing of FUTEX_WAIT.  PRs for these specific issues:
 
 PR kern/59129: futex(3): missing sign extension in FUTEX_WAKE_OP
 https://gnats.NetBSD.org/59129
 
 PR kern/59132: t_futex_ops:futex_wait_timeout_* sometimes fails on
 early wakeup
 https://gnats.NetBSD.org/59132
 
 Can you please try again with a current kernel, and let me know how
 (a) sysutils/tsm8,
 (b) the java pdf application, and
 (c) the ltp tests
 work with the changes?
 
 If things are still broken, I guess I'll have to look closer at the
 full ktrace.
