Subject: [PATCH 3.18-rc3 v3 0/2] trace: kdb: Bug fixes for ftdump

This patchset makes it possible to use kdb's ftdump command without
panicing, crashing or livelocking. The ftdump command cannot be used
at all without these changes.

IIRC this patches are still pending Jason's ack.

v3:

* Remove lines leading with --- from the patch comments, now it it
  -~- cut here -~- and "git am" did the right thing when I checked
  (Steven Rostedt)

v2:

* Fixed use-after-free problems in v1 by adding logic to NULL out
  buffer_iter during free operations.

* Introduced a second patch to fix a live lock when trying to display
  an empty trace buffer.
