      With WARN_ON addition to kobject_init()
      [ http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.19/2.6.19-mm1/dont-use/broken-out/gregkh-driver-kobject-warn.patch ]
      I started seeing following WARNING on CPU offline followed by online on my
      x86_64 system.
      WARNING at lib/kobject.c:172 kobject_init()
      Call Trace:

      DWARF2 unwinder stuck at system_call+0x7e/0x83
      Leftover inexact backtrace:
      This is a false positive as mce.c is unregistering/registering sysfs
      interfaces cleanly on hotplug.
      kref_put() and conditional decrement of refcnt seems to be the root cause
      for this and the patch below resolves the issue for me.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
