  Modified files:
    sys/kern             vfs_cache.c 
  Log:
   - Simplify the cache locking.  The lock order relationship with the
     vnode lock is much simpler than I originally thought it would be.
     Now, the cache lock is  always acquired before the vnode lock.
   - Provide some gotos in __getcwd() to simplify the unlocking a bit.
   - Move Giant acquisition down into __getcwd().
