The chip can issue spurious interrupts for single interrupt
modes. We use disable to clear the condition and allow processing to
continue. Also got rid of legacy specific code since it now needs to
be done on MSI single irq also.

This patch extends the critical regions covered by lp->lock to make it
safer on SMP. The main failure point was the smc911x_hard_start_xmit
function being called from different CPUs. It was tested on the ARM SMP
platforms.

Platforms like ARM Ltd's RealView require the IRQ polarity bit to be set
for the SMC9118 chip. This patch allows the dynamic configuration via
the smc911x_platdata structure.
This patch also changes the smc91x_platdata structure name to the
correct smc911x_platdata in the smc911x_drv_probe() function.

The 8139 drivers are a source of error messages that confuse users.
Since this device can not be disambiguated by normal PCI device
id's two drivers match the same info. But the module utilities
seem to correctly handle this overlap, they try one driver, then
if that doesn't load try the other. Therefore there is no need for
a message to be logged with error level severity, just using info
level instead. Can't be completely silent because user might have
configure one driver and forgot the other one.

Add a bool IGB_DCA defined to y if IGB and DCA are enabled, but IGB isn't y while DCA=m. And thus remove the need to select INTEL_IOATDMA when IGB is enabled, so that non-x86 architectures can build the igb driver.

Commit 147e70e6 ("cxgb3: Use SKB list interfaces instead of home-grown
implementation.") causes a crash in t3_l2t_send_slow() when an iWARP
connection request is received. This is because the new l2t_entry.arpq
skb queue is never initialized, and therefore trying to add an skb to
it causes a NULL dereference. With the old code there was no need to
initialize the queues because the l2t_entry structures were zeroed,
and the code used NULL to mean empty.
Fix this by adding __skb_queue_head_init() when all the l2t_entry
structures get allocated.

We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without
swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches
to combine them). I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup)
go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too?
But caution says still depend on MMU, since !CONFIG_MMU is.. different.

This gets rid of an annoying warning in ehci-hcd.c when DEBUG isn't

Yes, this will probably be switched over to a cleaner model anyway, but
in the meantime I don't want to see the 'unused variable' warnings that
come from the disgusting #ifdef code. Make the special case be a nice
inlien function of its own, clean up the code, and make the warning go
away.
I wish people didn't write code that gets (valid) warnings from the
compiler, but I'll limit my fixes to code that I actually care about (in
this case just because I see the warning and it annoys me).

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.
The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]). The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

This adds the ability to mmap legacy IO space to the legacy_io files
in sysfs on platforms that support it. This will allow to clean up
X to use this instead of /dev/mem for legacy IO accesses such as
those performed by Int10.

Since patch 6ac665c63dcac8fcec534a1d224ecbb8b867ad59 my infiniband

PCI_BASE_ADDRESS_MEM_PREFETCH.

whether the region is prefetchable or not is ignored. This fixes my
