f8059f7e67 m_split0(): If the newly allocated mbuf holds only the header, 
don't forget to set m_len to 0. Otherwise whatever will compute the size
of this chain (including s_split() itself if called again on this chain)
will get it wrong, leading to various issues.

Bug exposed by the NFS server code with linux clients using TCP mounts.

0cfa6e7487 Make the percpu API a little more friendly: 
- percpu_getptr() is now called percpu_getref() and implicitly disables
  preemption (via crit_enter()) when it is called.
- Added percpu_putref() which implicitly reenables preemption (via
  crit_exit()).
