Merge branch 'core/rcu' into perf/core 

Steve Rostedt asked for the merge of a single commit, into both
the RCU and the perf/tracing tree:

 | Josh made a change to the tracing code that affects both the
 | work Paul McKenney and I are currently doing. At the last
 | Kernel Summit back in August, Linus said when such a case
 | exists, it is best to make a separate branch based off of his
 | tree and place the change there. This way, the repositories
 | that need to share the change can both pull them in and the
 | SHA1 will match for both. Whichever branch is pulled in first
 | by Linus will also pull in the necessary change for the other
 | branch as well.

firmware assigned instance number of the PCI
device that can help in understanding the firmware
intended order of the PCI device.
What: /sys/bus/pci/devices/.../d3cold_allowed
Date: July 2012
Contact: Huang Ying <ying.huang@intel.com>
Description:
d3cold_allowed is bit to control whether the corresponding PCI
device can be put into D3Cold state. If it is cleared, the
device will never be put into D3Cold state. If it is set, the
device may be put into D3Cold state if other requirements are
satisfied too. Reading this attribute will show the current
value of d3cold_allowed bit. Writing this attribute will set
the value of d3cold_allowed bit.

Why: There are two mci drivers: at91-mci and atmel-mci. The PDC support
was added to atmel-mci as a first step to support more chips.
Then at91-mci was kept only for old IP versions (on at91rm9200 and
