Subject: [PATCH 0/4] Introduce a led trigger for CPU activity

Based on Linus Walleij's ARM LED consolidation work, this patchset introduce a
new generic led trigger for CPU not only for ARM but also for others.

For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to
trigger idle start or idle end event.

These 4 patches is against 3.0-rc4 and build successfully for versatile and
realview.

Bryan Wu (2):
  leds: create a trigger for CPU activity
  ARM: use new LEDS CPU trigger stub to replace old one

Linus Walleij (2):
  mach-realview: retire custom LED code
  mach-versatile: retire custom LED code
