                 - Check file systems that traverse mountpoint vnode lists.  
                   They need to use marker vnodes. Most already done.  
   
                 - Re-write the itimer code to be MP safe and work in the  
                   presence of threaded soft interrupts.

                   an old problem but either way it needs to be fixed.  
   
                 - UVM_FLAG_TRYLOCK is not sufficient in uvm_km.c because  
                   allocations will fail too often. It's needed for !kmem_map  
                   because sometimes allocations are made by threads that  
                   hold the map locked, which could cause other threads to  
                   wait long term even if they are trying to make a NOWAIT  
                   allocation.

                   - Minor locking improvements.
                   - Remove spinlockmgr().

   Notes:          This branch is for a general cleanup of all OEA-based PowerPC
                   ports. OEA (Operating Environment Architecture) PowerPC refers
                   to the 601, 603, 604, and similar chips.  Specifically, not the
                   403/401 and other embedded chips. The general concept is to get
                   them all compiling, and sharing as much code as possible.  All
                   developers are welcome to commit to this branch.
