[0/5] xen/vm-event: Cleanup

Message

Andrew Cooper June 3, 2019, 12:25 p.m. UTC

This came about from reviewing Petre's "Per vcpu vm_event channels" while sat
in an airport with plenty of time to kill.  This started with patch 4 trying
to get rid of the "k = i % d->max_vcpus;" expression, but see patch 4 for
further details of why it has stayed.

Everything else was either ancillary cleanup I noticed while reviewing, or
issues where were copied/moved/extended during the series.

This series can be obtained in git form from:

  http://xenbits.xen.org/gitweb/?p=people/andrewcoop/xen.git;a=shortlog;h=refs/heads/vmevent-cleanup-v1

There are no large functional changes, but it should be a better base to
refactor the interface from.
