Just like in the arch/sparc64/kernel/of_device.c code fix commit
071d7f4c3b411beae08d27656e958070c43b78b4 ("sparc64: Fix SMP bootup
with CONFIG_STACK_DEBUG or ftrace.") we have to check the OF device
node name for "pci" instead of relying upon the 'device_type' property
being there on all PCI bridges.
Tested by Meelis Roos, and confirmed to make the PCI QFE devices
reappear on the E3500 system.

Based upon a bug report by Meelis Roos.
The OF device layer builds properties by matching bus types and
applying 'range' properties as appropriate, up to the root.
The match for "PCI" busses is looking at the 'device_type' property,
and this does work %99 of the time.
But on an E3500 system with a PCI QFE card, the DEC 21153 bridge
sitting above the QFE network interface devices has a 'name' of "pci",
but it completely lacks a 'device_type' property. So we don't match
it as a PCI bus, and subsequently we end up with no resource values at
all for the devices sitting under that DEC bridge.

Based upon a report by Meelis Roos.
Any function call can try to access the current
thread register via the _mcount hooks when the kernel
is built with -pg (via ftrace or STACK_DEBUG).
That can't be setup properly very early on during
the bootup of other cpus for sun4u and some early
sun4v systems.
So add notrace markers to these specific functions, so
that _mcount doesn't get invoked too early.

We no longer put the top-level PCI controller device into the
PCI layer device list. So pbm->pci_bus->self is always NULL.
Therefore, use direct PCI config space accesses to get at
the PCI controller's PCI_STATUS register.

As noticed by Russell King, we were not setting this properly
to the number of entries, but rather the total size.
This results in the core dumping code allocating waayyyy too
much memory.

We need to pass IRQF_SHARED, otherwise we get things like:
IRQ handler type mismatch for IRQ 33

On a single board, the UE interrupts of two Psycho nodes

Decimal "33" mentioned above is the hex "21" mentioned here.
Thanks to Meelis Roos for dumps and testing.

When a CPU is offlined, we leave the timer interrupts disabled
because fixup_irqs() does not explicitly take care of that case.
Fix this by invoking tick_ops->disable_irq().

Make sparc64 refrain from clearing a given to-be-offlined CPU's bit in the
cpu_online_mask until it has processed pending irqs. This change
prevents other CPUs from being blindsided by an apparently offline CPU

This driver is now limited to just doing the basic clock board and FHC
chip initialization and registering the platform devices for the
per-board LEDs, which are driven by the new LEDS_STARFIRE driver.
