Provide basic support for MFDs having multiple cells of a given
type with different IDs by adding an id to the mfd_cell structure
and then adding that to the id passed in to mfd_add_devices().
As it stands this approach requires that MFDs using this feature
deal with ensuring that there aren't any ID collisions resulting
from multiple MFDs of the same type being instantiated. This needs
to happen with the existing code too, but with this approach there
is a knock on effect on the IDs for non-duplicated devices.

This patch corrects the support for MMCSD card detection
and read only feature for SoC DM355.
EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that
Bit 2 and 4 should be checked for card detection. However
on the EVM, bits 1 and 3 gives this status, for MMC/SD
instance 0 and 1 respectively. The pdf also suggests that
Bit 1 and 3 should be checked for write protection. However
on the EVM bits 2 and 4 gives this status.

Current implementation is prone to races, this patch attempts to remove all
but one (in pcf50633_adc_sync_read).
The idea is that we need to guard the queue access only on inserting and
removing items. If we insert and there're no more items in the queue it
means that the last irq already happened and we need to trigger ADC
manually. If not, then the next conversion will be triggered by the irq
handler upon completion of the previous.

Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.
I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

net/core/netpoll.c::netpoll_send_skb() calls the poll handler when

IRQ must not be enabled blindly in the NAPI handler of the driver
which supports netpoll.

When I was implementing primary_passive option (formely named primary_lazy) I've
run into troubles with ab_arp. This is the only mode which is not using
bond_select_active_slave() function to select active slave and instead it
selects it itself. This seems to be not the right behaviour and it would be
better to do it in bond_select_active_slave() for all cases. This patch makes
this happen. Please review.

Fixed up conflict in arch/powerpc/kernel/pci_64.c due to OF device tree

'needs_freset' initialization added in 6e19314cc ("PCI/powerpc: support
PCIe fundamental reset") is now in arch/powerpc/kernel/pci_of_scan.c.
The old code was using smp_call_function_many which skips the current
cpu if it is in the supplied cpumask. Switch to the rdmsr_on_cpus()
interface which takes care of that.
In addition, add get_cpus_on_this_dct_cpumask helper which computes a
cpumask of all the cores on a node and thus on a DCT.

Many years ago when this driver was written, it had a use, but these
days it's nothing but trouble and distributions should not enable it
in any situation.
Pretty much every console device a sparc machine could see has a
bonafide real driver, making the PROM console hack unnecessary.
If any new device shows up, we should write a driver instead of
depending upon this crutch to save us. We've been able to take care
of this even when no chip documentation exists (sunxvr500, sunxvr2500)
so there are no excuses.
