rtc: alarm: Add power-on alarm feature

Android does not support powering up of phone through alarm.
Adding shutdown hook in alarm driver which will set alarm while phone
is going down so as to power-up the phone after alarm expiration.

rtc: alarm: Set power-on alarm 120 sec before actual alarm time

This will add extra buffer time for booting-up the device before
actual alarm expiration time.

kernel: alarm: :fix the BUG that device automatically powers on

The value of alarm.time is invalid if we get it by:
    memset(&alarm, 0, sizeof(alarm)).
So function of rtc_set_alarm aborts before it really calls into:
    rtc->ops->set_alarm.
Then we can`t disable the RTC alarm by that. The result is some
alarms enabled by alarm_suspend are not disabled correctly during
alarm_resume. And device will automatically power on.

kernel: alarm: add dedicated alarm type for poweroff alarm

Now we use type of RTC_WAKEUP for the poweroff alarm.
Actually lots of other applications also use this type.
But these applications never expect the device will
power on after it has been shut down. So we need to
add dedicated alarm type for the Deskclock or similar
applications.

kernel: alarm: Do not call rtc_alarm_irq_enable in IRQ Disabled context

Currently shutdown hook of alarm driver is calling
the rtc_alarm_irq_enable API in interrupts disabled
context. So fix the alarm_shutdown function to call
in API rtc_alarm_irq_enable in interrupt enabled context.

rtc: alarm: have dummy set_power_on_alarm function

When !CONFIG_RTC_CLASS we need to have a dummy set_power_on_alarm
function. Otherwise, it is easy to have build issues.

rtc: alarm: init power_on_alarm_lock mutex in alarmtimer_rtc_timer_init

Moved mutex_init of power_on_alarm_lock into alarmtimer_rtc_timer_init
so that if CONFIG_RTC_CLASS is not enabled, we dont try to initialize
the mutex.  This fixes a build issue when !CONFIG_RTC_CLASS

mm: fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate number of
dirtyable pages/pages that can be allocated to the page cache.  A bug
causes an underflow thus making the page count look like a big unsigned
number.  This in turn confuses the dirty writeback throttling to
aggressively write back pages as they become dirty (usually 1 page at a
time).  This generally only affects systems with highmem because the
underflowed count gets subtracted from the global count of dirtyable
memory.

The problem was introduced with v3.2-4896-gab8fabd

Fix is to ensure we don't get an underflowed total of either highmem or
global dirtyable memory.
