	Subject: [PATCH] exynos4210: Fix race condition in idle states.

	1. Initially, only CPU0 is online.
	2. CPU0 starts to bring CPU1 online.
	3. CPU0 is waiting for CPU1 to come online, and meanwhile enters idle. Since it
	is the only online CPU, it lowers the CPU speed to save power.
	4. CPU1 goes online (NOTE: While CPU0 is still idling!)

	Subject: [PATCH 01/13] ARM: vfp: fix a hole in VFP thread migration

	Fix a hole in the VFP thread migration. Lets define two threads.

	Thread 1, we'll call 'interesting_thread' which is a thread which is
	running on CPU0, using VFP (so vfp_current_hw_state[0] =
	&interesting_thread->vfpstate) and gets migrated off to CPU1, where
