defconfigs: Add intellidemand
sched: Set MC (multi-core) sched domain's busy_factor attribute to 1

busy_factor attribute of a scheduler domain causes busy CPUs (CPUs
that are not idle) to load balance less frequently in that domain,
which could impact performance by increasing scheduling latency for
tasks.

As an example, consider MC scheduler domain's attribute values of
max_interval = 4ms and busy_factor = 64. Further consider
max_load_balance_interval = 100 (HZ/10). In this case, a non-idle CPU
could put off load balance check in MC domain by 100ms. This
effectively means that a CPU running a single task in its queue could
fail to notice increased load on another CPU (that is in same MC
domain) for upto 100ms, before picking up load from the overloaded
CPU. Needless to say, this leads to increased scheduling latency for
tasks, affecting performance adversely.

By setting MC domain's busy_factor value to 1, we limit maximum
interval that busy CPU can put off load balance checks to 4ms
(effectively 10ms, given HZ value of 100).

arm: vfp: always clear vfp_current_hw_state when forcing
 reload

The current thread trying to clear the held vfp state may not be
the owner of hw state. For example,
	Core0			Core1
				Thread1 uses VFP.
				  Thread1 vfpstate.hard.cpu = 1.
				  vfp_current_hw_state[1] points to Thread1
				    vfpstate.
	Going to suspend.
	Freeze Thread1.
				Thread1 is switched out.
				VFP HW registers saved to Thread1 vfpstate.
	Core0 disables Core1.
				Stopper thread calls vfp_force_reload().
				Stopper thread vfpstate.hard.cpu = NR_CPUS.
				...
				(No PM notifier for non-idle path. So
				  vfp_pm_suspend() is NOT called on Core1.)
				...
				Core1 is off and VFP HW registers are lost.
	...
	Core0 enables Core1.
	Core0 thaw Thread1.
	Thread1 migrate to Core1
	  before using VFP.
				Thread1 starts using VFP.
				Now we have vfp_current_hw_state[1] points
				  to Thread1 vfpstate. And Thread1 has
				  vfpstate.hard.cpu = 1.
				Thread1 does not need to reload saved vfpstate
				  to VFP HW.
				Thread1 continues running using corrupted VFP
				HW register.
This change fixes above gap by always clearing vfp_current_hw_state when
vfp_force_reload() is called.
