Linus Torvalds f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

Merge tag 'cleanup-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull sweeping late_initcall cleanup for arm-soc from Olof Johansson:
 "This is a patch series from Shawn Guo that moves from individual
  late_initcalls() to using a member in the machine structure to invoke
  a platform's late initcalls.

  This cleanup is a step in the move towards multiplatform kernels since
  it would reduce the need to check for compatible platforms in each and
  every initcall."

Fix up trivial conflicts in arch/arm/mach-{exynos/mach-universal_c210.c,
imx/mach-cpuimx51.c, omap2/board-generic.c} due to changes nearby (and,
in the case of cpuimx51.c the board support being deleted)
