  Log:
  MFC revision 1.130
    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.
