    Linus Torvalds authored
    Pull printk updates from Petr Mladek:
    
     - Add %pt[RT]s modifier to vsprintf(). It overrides ISO 8601 separator
       by using ' ' (space). It produces "YYYY-mm-dd HH:MM:SS" instead of
       "YYYY-mm-ddTHH:MM:SS".
    
     - Correctly parse long row of numbers by sscanf() when using the field
       width. Add extensive sscanf() selftest.
    
     - Generalize re-entrant CPU lock that has already been used to
       serialize dump_stack() output. It is part of the ongoing printk
       rework. It will allow to remove the obsoleted printk_safe buffers and
       introduce atomic consoles.
    
     - Some code clean up and sparse warning fixes.
