New Revision: 241734
URL: http://svn.freebsd.org/changeset/base/241734
Log:
Let SCHED_ULE give affinity to the CPU the tick interrupt triggered on
when running tick_process(), similarly to what the x86 equivalents of
this function do, however employing the less racy sequence also used in
intr_event_handle().
