The lock_system_sleep() function is used in the memory hotplug code at several places in order to implement mutual exclusion with hibernation. However, this function tries to acquire the 'pm_mutex' lock using mutex_lock() and hence blocks in TASK_UNINTERRUPTIBLE state if it doesn't get the lock. This would lead to task freezing failures and hence hibernation failure as a consequence, even though the hibernation call path successfully acquired the lock. But it is to be noted that, since this task tries to acquire pm_mutex, if it blocks due to this, we are *100% sure* that this task is not going to run as long as hibernation sequence is in progress, since hibernation releases 'pm_mutex' only at the very end, when everything is done. And this means, this task is going to be anyway blocked for much more longer than what the freezer intends to achieve; which means, freezing and thawing doesn't really make any difference to this task! So, to fix freezing failures, we just ask the freezer to skip freezing this task, since it is already "frozen enough". But instead of calling freezer_do_not_count() and freezer_count() as it is, we use only the relevant parts of those functions, because restrictions such as 'the task should be a userspace one' etc., might not be relevant in this scenario.

The hibernation core code forgets to release memory preallocated for hibernation if there's an error in its early stages or if test modes causing hibernation_snapshot() to return early are used. This causes the system to be hardly usable, because the amount of preallocated memory is usually huge. Fix this problem. Reported-by: NSrivatsa S.

Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: NAfzal Mohammed <afzal@ti.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

This reverts commit dc937280. As requested by Ben Herrenschmidt: "This breaks some powerpc platforms at least. The practice of having a node provide an explicit "interrupt-parent" property pointing to itself is an old trick that we've used in the past to allow a device-node to have interrupts routed to different controllers. In that case, the node also contains an interrupt-map, so the node is its own parent, the interrupt resolution hits the map, which then can route each individual interrupt to a different parent." Grant says: "Ah, nuts, yes that is broken then. Yes, please revert the commit and Rob & I will come up with a better solution. Rob, I think it can be done by explicitly checking for np == desc->interrupt_parent in of_irq_init() instead of relying on of_irq_find_parent() returning NULL."
