Log:
   ck: add support for executing callbacks outside of main poll loop

   Pull in change from upstream deca119d14bfffd440770eb67cbdbeaf7b57eb7b

   |    ck_epoch: introduce ck_epoch_deferred
   |
   |    Allow for deferral to occur outside epoch poll critical loop (which may 
access per-CPU structures).

   Approved by:        sbruno

Modified:
   head/sys/contrib/ck/include/ck_epoch.h
   head/sys/contrib/ck/src/ck_epoch.c

  CK was imported in vendor-sys/ck, commiting directly into head will
cause some problems in the future.

Actually ... committing to head is fine: some things just have to be fixed.
We do ask you try to upstream the change and re-merge things when possible.

Pedro.
