 1.12  17-Mar-2017  wiz Bump date for previous.
 1.11  16-Mar-2017  chs allow pcu_save() and pcu_discard() to be called on other threads,
ptrace needs to use it that way.
 1.10  25-May-2014  rmind branches: 1.10.6; 1.10.10;
pcu(9) man page: correct PCU_REENABLE description, add pcu_discard_all(),
improve some wording.
 1.9  16-May-2014  wiz Consistency.
 1.8  16-May-2014  martin Add missing .Bl
 1.7  16-May-2014  rmind pcu(9):
- Remove PCU_KERNEL (hi matt!) and significantly simplify the code.
This experimental feature was tried on ARM did not meet the expectations.
It may be revived one day, but it should be done in a much simpler way.
- Add a message structure for xcall function, pass the LWP ower and thus
optimise a race condition: if LWP is discarding its state on a remote CPU,
but another LWP already did it - do not cause an unecessary re-faulting.
- Reduce the variety of flags for PCU operations (only PCU_VALID and
PCU_REENABLE are used now), pass them only to the pcu_state_load().
- Rename pcu_used_p() to pcu_valid_p(); hopefully it is less confusing.
- pcu_save_all_on_cpu: SPL ought to be used here.
- Update and improve the pcu(9) man page; it needs wizd(8) though.
