MMA8451 is very noisy even when idle as it has no hysteresis on

This is a fix for the fishing master app stopping on a single
touch event. The fishing master app has another issue that it
dies on 2 touch events, which is an app implementation issue.

Disable the clock when the uart port is not used.

These methods are invoked if the iMX uart is used in conjuction with kgdb during
early boot. In order to access the UART without the interrupts, the kernel uses
the basic polling methods for IO with the device. With these methods
implemented, it is now possible to enable kgdb during early boot over serial.

Since the port->lock has already been hold when enter rx_interrupt,
and thus hold it on during handle_sysrq. We need check whether the
current console_write is for the sysrq message output or not and use
the correct lock mechanism.

In the cd_irq, we are resetting the SDHC controller but not
resetting the card. As per specification, if host driver resets the
controller, it should reset the card too. Removed the host reset
from cd_irq and enable multi-block transfer using ACMD23 instead of
ACMD12.

sdma: bd is bufferable dma buffer, interrupt handler can not get correct
data after sdma script updated. Which will cause there is no interrupt
after failed period number times in the interrupt handler.
This is a workaround.

We found some wired crash in the SLUB managed list, but it's too wired to fix.
Althrough we found almost all ARM platform using SLAB,
maybe it's because it's not very stable on ARM platform,
so we change to SLAB too.

Stepan found:

/* wait-forever-more */
<PREEMPT-in>
local_irq_enable()
cpu_notify(CPU_ONLINE)
sched_cpu_active()
set_cpu_active()
Now the purpose of cpu_active is mostly with bringing down a cpu, where
we mark it !active to avoid the load-balancer from moving tasks to it
while we tear down the cpu. This is required because we only update the
sched_domain tree after we brought the cpu-down. And this is needed so
that some tasks can still run while we bring it down, we just don't want
new tasks to appear.
On cpu-up however the sched_domain tree doesn't yet include the new cpu,
so its invisible to the load-balancer, regardless of the active state.
So instead of setting the active state after we boot the new cpu (and
consequently having to wait for it before enabling interrupts) set the
cpu active before we set it online and avoid the whole mess.

We can stall RCU processing on SMP platforms if a CPU sits in its idle
loop for a long time. This happens because we don't call irq_enter()
and irq_exit() around generic_smp_call_function_interrupt() and
friends. Add the necessary calls, and remove the one from within
ipi_timer(), so that they're all in a common place.

In ARIK, to prevent noise cause by false triggered burst, we reduce
