The dev_kfree_skb in islpci_eth_transmit happens while irqs are still
disabled, so either dev_kfree_skb_irq needs to be used or the skb
needs to be freed after irqs have been enabled again. This patch
should fix it.

This one from my DMA_{32,64}BIT_MASK series did not seem to make it
through to upstream.
Use the DMA_{32,64}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
This patch includes dma-mapping.h explicitly because it caused errors
on some architectures otherwise.

The latest kernel added a pretty ugly fix for the orinoco etherleak bug
which contains bogus skb->len checks already done by the caller and causes
copies of all odd sized frames (which are quite common)
While the skb->len check should be ripped out the other fix is harder to do
properly so I'm proposing for this the -mm tree only until next 2.6.x so
that it gets tested.
Instead of copying buffers around blindly this code implements a padding
aware version of the hermes buffer writing function which does padding as
the buffer is loaded and thus more cleanly and without bogus 1.5K copies.

e1000_suspend is only used under #ifdef CONFIG_PM. Move the declaration of
it to be the same way, just like e1000_resume, otherwise gcc whines on
compile. I offer as evidence:
static struct pci_driver e1000_driver = {
.name = e1000_driver_name,
.id_table = e1000_pci_tbl,
.probe = e1000_probe,
.remove = __devexit_p(e1000_remove),
/* Power Managment Hooks */
#ifdef CONFIG_PM
.suspend = e1000_suspend,
.resume = e1000_resume
#endif
};

1) Forgotten counter incrementation in sis900_rx() in case
it doesn't get memory for skb, that leads to whole interface failure.
Problem is accompanied with messages:
eth0: Memory squeeze,deferring packet.
eth0: NULL pointer encountered in Rx ring, skipping
2) If counter cur_rx overflows and there'll be temporary memory problems
buffer can't be recreated later, when memory IS available.
3) Limit the work in handler to prevent the endless packets processing
if new packets are generated faster then handled.

This patch replaces current PowerPC 4xx EMAC driver with
new, re-written from the scratch version. This patch is quite big
(~234K) because there is virtualy 0% of common code between old and
new version.
New driver uses NAPI, it solves stability problems under heavy packet
load and low memory, corrects chip register access and fixes numerous
small bugs I don't even remember now.
This patch has been tested on all supported in 2.6 PPC 4xx boards.
It's been used in production for almost a year now on custom
4xx hardware. PPC32 specific parts are already upstream.
Patch was acked by the current EMAC driver maintainer (Matt Porter). I
will be maintaining this new version.

This patch fixes a bug that happens when the hypervisor can't add a
buffer. The old code wrote IBM_VETH_INVALID_MAP into the free_map
array, so next time the index was used, a ibmveth_assert() caught it and
called BUG(). The patch writes the right value into the free_map array
so that the index can be reused.

This patch removes the allocation of RX skb's buffers from a workqueue
to be called directly at RX processing time. This change was suggested
by Dave Miller when the driver was starving the RX buffers and
deadlocking under heavy traffic:
> Allocating RX SKBs via tasklet is, IMHO, the worst way to
> do it. It is no surprise that there are starvation cases.
>
> If tasklets or work queues get delayed in any way, you lose,
> and it's very easy for a card to catch up with the driver RX'ing
> packets very fast, no matter how aggressive you make the
> replenishing. By the time you detect that you need to be
> "more aggressive" it is already too late.
> The only pseudo-reliable way is to allocate at RX processing time.

This patch changes the way the ibmveth driver handles the receive
buffers. The old code mallocs and maps all the buffers in the pools
regardless of MTU size and it also limits the number of buffer pools to
three. This patch makes the driver malloc and map the buffers necessary
to support the current MTU. It also changes the hardcoded names of the
buffer pool number, size, and elements to arrays to make it easier to
change (with the hope of making them runtime parameters in the future).

Change the ASF heart beat to 5 seconds for faster detection of system
crash. The driver sends the heartbeat every 2 seconds and the ASF
firmware will timeout and reset the device if no heartbeat is received
after 5 seconds. The old scheme of 2 minutes is ineffective.
tg3_write_mem_fast() is added to speed up the IO to send the heartbeat.
When no workaround is needed, it will use direct MMIO to memory space
to write to memory.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.
