History
Jeff Roberson 22bf7d9a0e - Add static to local functions and data where it was missing. 
- Add an IPI based mechanism for migrating kses.  This mechanism is
   broken down into several components.  This is intended to reduce cache
   thrashing by eliminating most cases where one cpu touches another's
   run queues.
 - kseq_notify() appends a kse to a lockless singly linked list and
   conditionally sends an IPI to the target processor.  Right now this is
   protected by sched_lock but at some point I'd like to get rid of the
   global lock.  This is why I used something more complicated than a
   standard queue.
 - kseq_assign() processes our list of kses that have been assigned to us
   by other processors.  This simply calls sched_add() for each item on the
   list after clearing the new KEF_ASSIGNED flag.  This flag is used to
   indicate that we have been appeneded to the assigned queue but not
   added to the run queue yet.
 - In sched_add(), instead of adding a KSE to another processor's queue we
   use kse_notify() so that we don't touch their queue.  Also in sched_add(),
   if KEF_ASSIGNED is already set return immediately.  This can happen if
   a thread is removed and readded so that the priority is recorded properly.
 - In sched_rem() return immediately if KEF_ASSIGNED is set.  All callers
   immediately readd simply to adjust priorites etc.
 - In sched_choose(), if we're running an IDLE task or the per cpu idle thread
   set our cpumask bit in 'kseq_idle' so that other processors may know that
   we are idle.  Before this, make a single pass through the run queues of
   other processors so that we may find work more immediately if it is
   available.
 - In sched_runnable(), don't scan each processor's run queue, they will IPI
   us if they have work for us to do.
 - In sched_add(), if we're adding a thread that can be migrated and we have
   plenty of work to do, try to migrate the thread to an idle kseq.
 - Simplify the logic in sched_prio() and take the KEF_ASSIGNED flag into
   consideration.
 - No longer use kseq_choose() to steal threads, it can lose it's last
   argument.
 - Create a new function runq_steal() which operates like runq_choose() but
   skips threads based on some criteria.  Currently it will not steal
   PRI_ITHD threads.  In the future this will be used for CPU binding.
 - Create a kseq_steal() that checks each run queue with runq_steal(), use
   kseq_steal() in the places where we used kseq_choose() to steal with
   before.
