To support IOAPIC hotplug, we need to correctly manage IOAPIC pin usage,
which is to allocate IRQs on demand and free them when not used anymore.
So use pcibios_alloc_irq() and pcibios_free_irq() to dynamically allocate
and free PCI IRQs.
Also remove obseleted code mp_should_keep_irq().
Add three helpers to manage pci_dev->irq and pci_dev->irq_managed,
which helps to improve maintenance.

The current version of PWM regulator only supports a static table
approach, where pre-calculated values are supplied by the vendor and
obtained via DT. The continuous-voltage method takes min_uV and
max_uV, and divides the difference between them up into a number of
slices. The number of slices
Continuous mode uses the PWM regulator's maximum and minimum supplied
voltages specified in the regulator-{min,max}-microvolt properties to
calculate appropriate duty-cycle values. This allows for a much more

Full sync for drbd initial usually take a long time, especically
when network become the bottleneck the syncing. Simply skip the
full sync with "--clear-bitmap" may not the perfect solution
for all the cases. So this patches can be used to zero out
devices locally instead of a full sync,two make

Kexec_load syscall in ARM requires that machine-specific code
has the smp_ops.cpu_kill() before loading kernel image.
This patch adds the cpu_kill(), as a result, kexec reboot and
kernel crash dump become available in mach-socfpga.

Please funnel this through the ARM SoC tree.

Looks fine, but does it make any difference?

Hi Vishal,
I'm mostly worried about handling scalability to large CPU counts
properly. If you think this is the best way to handle it that fine,
but please document the decisions on the changelog in a similar form
