Many drivers use skb->tail unnecessarily.
In these situations, the code roughly looks like:
dev = dev_alloc_skb(...);
[optional] skb_reserve(skb, ...);
... skb->tail ...
But even if the skb_reserve() happens, skb->data equals
skb->tail. So it doesn't make any sense to use anything
other than skb->data in these cases.
Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers. It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.
Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge. In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

Now we can change the pci core to always set this pointer, as pci drivers
should use it, not the driver core callback.

More fixes for greg depredations.
Also nuke lots of pointless typecasts.
All this new wireless code adds near-infinite amounts of trailing whitespace.

Fix few typos/thinkos in ipw, remove ugly macro (it is commented around,
anyway), and fix types passed to pci_set_power_state.

ipw2100 still has support for old kernels. Thats considered bad for patch in

Use the DMA_32BIT_MASK constant from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask() instead of custom macros.
This patch includes dma-mapping.h explicitly because it caused errors on some
architectures otherwise. See

Thanks. This is a corrected version of the patch.

This results in recursive dependencies:
- IPW2200 depends on NET_RADIO
- IPW2200 selects IEEE80211
- IEEE80211 selects NET_RADIO
This patch fixes the IPW2200 dependencies in a way that they are similar
to the IPW2100 dependencies.

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.
I do not own this device so I only compile-tested this patch.

For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it),
the set_irq_type() call can't assume IRQT_RISING. These particular
boards currently use OMAP-specific calls to change the trigger type,
but the boards break when set_irq_type() stops being a NOP.
