  Modified files:
    sys/vm               uma_core.c 
  Log:
  Introduce a new lock for the purpose of synchronizing access to the
  UMA boot pages.
  
  Disable recursion on the general UMA lock now that startup_alloc() no
  longer uses it.
  
  Eliminate the variable uma_boot_free.  It serves no purpose.
  
  Note: This change eliminates a lock-order reversal between a system
  map mutex and the UMA lock.  See
  http://sources.zabbadoz.net/freebsd/lor.html#109 for details.
