Subject: [PATCH 0/2 V4] Print traces on softlockup

Added more patches to handle the 'uniprocessor' panic case by sending NMIs
to every cpu but self.  Only affects x86, sparc.

V4: roll x86 and sparc patches into patch1
    add CONFIG_SMP in various places based on Andrew's suggestion
V3: wrap x86 code with get/put_cpu based on Oleg's suggestions
V2: expand from one patch to 4

Aaron Tomlin (4):
  nmi: Provide the option to issue an NMI back trace to every cpu but
    current
  x86, nmi: Add more flexible NMI back trace support
  sparc64, nmi: Add more flexible NMI back trace support
  watchdog: Printing traces for all cpus on lockup detection
