Merge branch 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc

Pull OLPC platform updates from Andres Salomon:
 "These move the OLPC Embedded Controller driver out of
  arch/x86/platform and into drivers/platform/olpc.

  OLPC machines are now ARM-based (which means lots of x86 and ARM
  changes), but are typically pretty self-contained..  so it makes more
  sense to go through a separate OLPC tree after getting the appropriate
  review/ACKs."

* 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc:
  x86: OLPC: move s/r-related EC cmds to EC driver
  Platform: OLPC: move global variables into priv struct
  Platform: OLPC: move debugfs support from x86 EC driver
  x86: OLPC: switch over to using new EC driver on x86
  Platform: OLPC: add a suspended flag to the EC driver
  Platform: OLPC: turn EC driver into a platform_driver
  Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it
  drivers: OLPC: update various drivers to include olpc-ec.h
  Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver
