Some typos led to using %i6/%i7 instead of %l6/%l7 in loads which is
really really bad because those are the frame pointer and return PC.

This also makes us use the MSI queues correctly.
Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt
handler. This handler runs the MSI queue and dispatches the
virtual interrupts indicated by arriving MSIs in that MSI queue.
All of the common logic is placed in pci_msi.c, with callbacks to
handle the PCI controller specific aspects of the operations.
This common infrastructure will make it much easier to add MSG
support.

Thanks to Tom Callaway for the excellent bug report and
test case.
sys_ipc() has several problems, most to due with semaphore
call handling:
1) 'err' return should be a 'long'
2) "union semun" is passed in a register on 64-bit compared
to 32-bit which provides it on the stack and therefore
by reference
3) Second and third arguments to SEMCTL are swapped compared
to 32-bit.

The name field of of_platform_driver is just copied into the
included device_driver. By not overriding an already initialised
device_driver name, we can convert the drivers over time to stop using
the of_platform_driver name.
Also we were not copying the owner field from of_platform_driver, so do
the same with it.

Added asm-sparc/irqflags.h and moved irq related code from system.h to it.
Renamed local_irq functions to raw_local_irq in irq.c.
Modified system.h to include linux/irqflags.h which includes asm/irqflags.h.
Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.
This is the first step in adding IRQ-flags state tracing as outlined in
Documentation/irqflags-tracing.txt. These changes should be harmless
because they just move things around and rename them.
The next step is making the lowlevel entry code modifications which
to be honest are beyond my capabilities at this point.

Use _CRS for PCI resource allocation
This patch resolves an issue where incorrect PCI memory and i/o ranges
are being assigned to hotplugged PCI devices on some IBM systems. The
resource mis-allocation not only makes the PCI device unuseable but
often makes the entire system unuseable due to resulting machine checks.
The hotplug capable PCI slots on the affected systems are not located
under a standard P2P bridge but are instead located under PCI root
bridges or subtractive decode P2P bridges. For example, the IBM x3850
contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots
with the PCI-X slots each located under a PCI root bridge and the PCIe
slots each located under a subtractive decode P2P bridge.
The current i386/x86_64 PCI resource allocation code does not use _CRS
returned resource information. No other resource information source is
available for slots that are not below a standard P2P bridge so
incorrect ranges are being allocated from e820 hole causing the bad
result.
This patch causes the kernel to use _CRS returned resource info. It is
roughly based on a change provided by Matthew Wilcox for the ia64 kernel
in 2005. Due to possible buggy BIOS factor and possible yet to be
discovered kernel issues the function is disabled by default and can be
enabled with pci=use_crs.

Skip ISA ioresource alignment on some systems
To conserve limited PCI i/o resource on some IBM multi-node systems, the
BIOS allocates (via _CRS) and expects the kernel to use addresses in
ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c].
This change allows the kernel to use the currently excluded address
ranges on the IBM x3800, x3850, and x3950.

On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish
call context requirement: unlike its dma_alloc_coherent() sibling, it may
not be called with IRQs disabled. (This was new behavior on ARM as of late
2005, caused by ARM SMP updates.) This little surprise can be annoyingly
driver-visible.
Since it looks like that restriction won't be removed, this patch changes
the definition of the API to include that requirement. Also, to help catch
nonportable drivers, it updates the x86 and swiotlb versions to include the
relevant warnings. (I already observed that it trips on the
bus_reset_tasklet of the new firewire_ohci driver.)
