    Merge branch 'anton-kgdb' (kgdb dmesg fixups) · 9a2bc860

    Merge emailed kgdb dmesg fixups patches from Anton Vorontsov:
     "The dmesg command appears to be broken after the printk rework.  The
      old logic in the kdb code makes no sense in terms of current
      printk/logging storage format, and KDB simply hangs forever upon
      entering 'dmesg' command.
    
      The first patch revives the command by switching to kmsg_dumper
      iterator.  As a side-effect, the code is now much more simpler.
    
      A few changes were needed in the printk.c: we needed unlocked variant
      of the kmsg_dumper iterator, but these can surely wait for 3.6.
    
      It's probably too late even for the first patch to go to 3.5, but I'll
      try to convince otherwise.  :-) Here we go:
    
       - The current code is broken for sure, and has no hope to work at
         all.  It is a regression
       - The new code works for me, and probably works for everyone else;
       - If it compiles (and I urge everyone to compile-test it on your
         setup), it hardly can make things worse."
