vm_clock is the same as rt_clock as long as: 1) you don't use -icount;
2) you don't stop the VM.

Not pulsing the LED when the VM is stopped seems okay, so I think
switching from rt_clock to vm_clock is the right thing to do.

You should get this from -icount if you just use vm_clock.

The overall series doesn't apply anymore, I'll split omap_lpg into its
own patch and resend.
