[GIT PULL] big.LITTLE switcher support, part 2

[Nicolas Pitre]

Russell, please pull the following:

  git://git.linaro.org/people/nico/linux iks_for_rmk

This is the second set of patches towards a fully functional and 
production quality switcher solution for big.LITTLE systems, 
establishing a landmark to compare against for any scheduler based 
solution meant to eventually surpass the switcher's power efficiency 
available in the mainline kernel.

This is based on your devel-stable as of now in order to get the first
set of patches.

The shortlog and diffstat follow:

Dave Martin (7):
      ARM: bL_switcher: Add synchronous enable/disable interface
      ARM: bL_switcher: Add runtime control notifier
      ARM: bL_switcher: Add switch completion callback for bL_switch_request()
      ARM: bL_switcher: Basic trace events support
      ARM: bL_switcher/trace: Add trace trigger for trace bootstrapping
      ARM: bL_switcher/trace: Add kernel trace trigger interface
      ARM: bL_switcher: Add query interface to discover CPU affinities

Nicolas Pitre (6):
      ARM: bL_switcher: synchronize the outbound with the inbound
      ARM: SMP: basic IPI triggered completion support
      ARM: mcpm: add a simple poke mechanism to the early entry code
      ARM: GIC: function to retrieve the physical address of the SGIR
      ARM: GIC: interface to send a SGI directly
      ARM: bL_switcher: wait until inbound is alive before performing a switch
