38bddf04bcfe661fbdab94888c3b72c32f6873b3 gianfar: gfar_remove needs to call unregister_netdev()

breaks the build of the gianfar driver because "dev" is undefined in
this function. To quickly test rc9 I changed this to priv->ndev but I do
not know if this is the correct one.

Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure
for ipw2200 firmware loading in kernel 2.6.30. High order allocation is
likely to fail and should always be avoided.

The patch fixes this problem by replacing the original order-6
pci_alloc_consistent() with an array of order-1 pages from a pci pool.
This utilized the ipw2200 DMA command blocks (up to 64 slots). The
maximum firmware size support remains the same (64*8K).

This patch fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=14016

If we run out of memory, use keventd to fill the buffer.  There's a
report of this happening: "Page allocation failures in guest",

The NETPOLL requires that interrupts remain disabled in its callbacks.

Using *_irq_save()/irq_restore() to replace *_irq_disable()/irq_enable()
functions in NETPOLL's callbacks of smc91x, so that it doesn't enable
interrupts when already disabled, and kgdboe/netconsole would work
properly over smc91x.

This patch fixes broken pxaficp-ir. The problem was in incorrect
net_device_ops being specified which prevented the driver from
operating. The symptoms were:
 - failing ifconfig for IrLAN, resulting in
	SIOCSIFFLAGS: Cannot assign requested address
 - irattach working for IrCOMM, but the port stayed disabled

Moreover this patch corrects missing sysfs device link.
