689be43945 [NET]: Remove gratuitous use of skb->tail in network drivers.
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.

97f568d8e3 8139cp: safer spin loop for get_statistics
The spin loop in 8139cp is limited to 100 iterations when pulling hardware
stats. There is no allowance for processor speed so on a fast machine, the
stats may not be available that fast. Also, if the board doesn't return
soon enough make sure turn the address back off to prevent later updates
when memory has gone away.

8662d06171 [PATCH] drivers/net/8139cp: Use the DMA_{64, 32}BIT_MASK constants
The previous patch did not compile cleanly on all architectures so
  here's a fixed one.
  
  Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
  pci_set_dma_mask() or pci_set_consistent_dma_mask()

7502cd1058 [PATCH] 8139cp - add netpoll support
Patch adds netpoll support to the 8139cp driver.
  The patch needs some tests because I have no NIC of this type for testing.
  
  Applies against linux-2.6.9-rc2-mm3

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
